We can now easily fetch and merge things from heads in the
refs/remotes/ hierarchy in remote repositories.
The refs/remotes/ hierarchy is likely to become the standard for
tracking foreign SCMs, as well as the location of Pull: targets
for tracking remote branches in newly cloned repositories.

Unless --no-tags flag was given, git-fetch tried to always
follow remote tags that point at the commits we picked up.
It is not very useful to pick up tags from remote unless storing
the fetched branch head in a local tracking branch. This is
especially true if the fetch is done to merge the remote branch
into our current branch as one-shot basis (i.e. "please pull"),
and is even harmful if the remote repository has many irrelevant
tags.
This proposed update disables the automated tag following unless
we are storing the a fetched branch head in a local tracking
branch.

When doing something like
git fetch --tags origin
the excessively verbose output of git fetch makes the result totally
unreadable. It's impossible to tell if it actually fetched anything new or
not, since the screen will fill up with an endless supply of
...
* committish: 9165ec17fd
tag 'v0.99.7c' of master.kernel.org:/pub/scm/git/git
* refs/tags/v0.99.7c: same as tag 'v0.99.7c' of master.kernel.org:/pub/scm/git/git
...
and any new tags that got fetched will be totally hidden.
So add a new "--verbose" flag to "git fetch" to enable this verbose mode,
but make the default be quiet.
NOTE! The quiet mode will still report about new or changed heads, so if
you are really fetching a new head, you'll see something like this:
[torvalds@g5 git]$ git fetch --tags parent
Packing 6 objects
Unpacking 6 objects
100% (6/6) done
* refs/tags/v1.0rc2: storing tag 'v1.0rc2' of master.kernel.org:/pub/scm/git/git
* refs/tags/v1.0rc3: storing tag 'v1.0rc3' of master.kernel.org:/pub/scm/git/git
* refs/tags/v1.0rc1: storing tag 'v1.0rc1' of master.kernel.org:/pub/scm/git/git
which actually tells you something useful that isn't hidden by all the
useless crud that you already had.
Extensively tested (hey, for me, this _is_ extensive) by doing a
rm .git/refs/tags/v1.0rc*
and re-fetching with both --verbose and without.
NOTE! This means that if the fetch didn't actually fetch anything at all,
git fetch will be totally quiet. I think that's much better than being so
verbose that you can't even tell whether something was fetched or not, but
some people might prefer to get a "nothing to fetch" message in that case.

tag information to help Martin's findtags and possibly later

For local operations and downloading and uploading via git aware protocols,

However, dumb protocols and rsync transport needs to resolve this on the

(2) Many command names with 'cache' in them are renamed with
'index' if that is what they mean.

When the "git pull" command updates the branch head you are
currently on, before doing anything else, first update your
index file and the working tree contents to that of the new
branch head. Otherwise, the later resolving steps would think
your index file is attempting to revert the change between the
original head commit and the updated head commit.
It uses two-tree fast-forward form of "read-tree -m -u" to
prevent losing whatever local changes you may have in the
working tree to do this update. I think this would at least
make things safer (a lot safer), and prevent mistakes.
Also "git fetch" command is forbidden from fetching and fast
forwarding the current branch head unless --update-head-ok flag
is given. "git pull" passes the flag when it internally calls
"git fetch".

instead of barfing.

explicit refspecs are specified, and did not make sure we know
what "origin" means before defaulting to it.]

Traditionally, fetch takes these forms:
$ git fetch <remote>
$ git fetch <remote> <head>
$ git fetch <remote> tag <tag>
This patch updates it to take
$ git fetch <remote> <refspec>...
where:
- A <refspec> of form "<src>:<dst>" is to fetch the objects
needed for the remote ref that matches <src>, and if <dst>
is not empty, store it as a local <dst>.
- "tag" followed by <next> is just an old way of saying
"refs/tags/<next>:refs/tags/<next>"; this mimics the
current behaviour of the third form above and means "fetch
that tag and store it under the same name".
- A single token <refspec> without colon is a shorthand for
"<refspec>:" That is, "fetch that ref but do not store
anywhere".
- when there is no <refspec> specified
- if <remote> is the name of a file under $GIT_DIR/remotes/
(i.e. a new-style shorthand), then it is the same as giving
the <refspec>s listed on Pull: line in that file.
- if <remote> is the name of a file under $GIT_DIR/branches/
(i.e. an old-style shorthand, without trailing path), then it
is the same as giving a single <refspec>
"<remote-name>:refs/heads/<remote>" on the command line, where
<remote-name> is the remote branch name (defaults to HEAD, but
can be overridden by .git/branches/<remote> file having the
URL fragment notation). That is, "fetch that branch head and
store it in refs/heads/<remote>".
- otherwise, it is the same as giving a single <refspec>
that is "HEAD:".
The SHA1 object names of fetched refs are stored in FETCH_HEAD,
one name per line, with a comment to describe where it came from.
This is later used by "git resolve" and "git octopus".

This is a beginning of resurrecting the multi-head pulling support
for git-fetch-pack command. The git-fetch-script wrapper still

not very useful unless you directly call git-fetch-pack itself yet.

We were trying to fetch using the merge-head name rather than the
merge-head SHA1 that we just got.
Now, http:// is broken anyway right now for packing, but this should
make it work for nonpacked repositories again.
Since pull and fetch are done often against the same remote
repository repeatedly, keeping the URL to pull from along with
the name of the head to use in $GIT_DIR/branches/$name makes a
lot of sense. Adopt that convention from Cogito, and try to be
compatible when possible; storing a partial URL and completing
it with a trailing path may not be understood by Cogito.
While we are at it, fix pulling a tag. Earlier, we updated only
refs/tags/$tag without updating FETCH_HEAD, and called
resolve-script using a stale (or absent) FETCH_HEAD.
