Stefan Naewe 986bbc0842 http: don't always prompt for password
When a username is already specified at the beginning of any HTTP
transaction (e.g. "git push https://user@hosting.example.com/project.git"
or "git ls-remote https://user@hosting.example.com/project.git"), the code
interactively asks for a password before calling into the libcurl library.
It is very likely that the reason why user included the username in the
URL is because the user knows that it would require authentication to
access the resource. Asking for the password upfront would save one
roundtrip to get a 401 response, getting the password and then retrying
the request. This is a reasonable optimization.

HOWEVER.

This is done even when $HOME/.netrc might have a corresponding entry to
access the site, or the site does not require authentication to access the
resource after all. But neither condition can be determined until we call
into libcurl library (we do not read and parse $HOME/.netrc ourselves). In
these cases, the user is forced to respond to the password prompt, only to
give a password that is not used in the HTTP transaction. If the password
is in $HOME/.netrc, an empty input would later let the libcurl layer to
pick up the password from there, and if the resource does not require
authentication, any input would be taken and then discarded without
getting used. It is wasteful to ask this unused information to the end
user.

Reduce the confusion by not trying to optimize for this case and always
incur roundtrip penalty. An alternative might be to document this and keep
this round-trip optimization as-is.

	GIT - the stupid content tracker

////////////////////////////////////////////////////////////////

"git" can mean anything, depending on your mood.

 - random three-letter combination that is pronounceable, and not
   actually used by any common UNIX command.  The fact that it is a
   mispronunciation of "get" may or may not be relevant.
 - stupid. contemptible and despicable. simple. Take your pick from the
   dictionary of slang.
 - "global information tracker": you're in a good mood, and it actually
   works for you. Angels sing, and a light suddenly fills the room.
 - "goddamn idiotic truckload of sh*t": when it breaks

Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.

Git is an Open Source project covered by the GNU General Public License.
It was originally written by Linus Torvalds with help of a group of
hackers around the net. It is currently maintained by Junio C Hamano.

Please read the file INSTALL for installation instructions.

See Documentation/gittutorial.txt to get started, then see
Documentation/everyday.txt for a useful minimum set of commands, and
Documentation/git-commandname.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with "man gittutorial" or "git help tutorial", and the
documentation of each command with "man git-commandname" or "git help
commandname".

CVS users may also want to read Documentation/gitcvs-migration.txt
("man gitcvs-migration" or "git help cvs-migration" if git is
installed).

Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.

The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org. To subscribe
to the list, send an email with just "subscribe git" in the body to
majordomo@vger.kernel.org. The mailing list archives are available at
http://marc.theaimsgroup.com/?l=git and other archival sites.

The messages titled "A note from the maintainer", "What's in
git.git (stable)" and "What's cooking in git.git (topics)" and
the discussion following them on the mailing list give a good
reference for project status, development direction and
remaining tasks.
