While Git has documented that the credential protocol is line-based,
with newlines as terminators, the exact shape of a newline has not been
documented.
From Git's perspective, which is firmly rooted in the Linux ecosystem,
it is clear that "a newline" means a Line Feed character.
However, even Git's credential protocol respects Windows line endings
(a Carriage Return character followed by a Line Feed character, "CR/LF")
by virtue of using `strbuf_getline()`.
There is a third category of line endings that has been used originally
by MacOS, and that is respected by the default line readers of .NET and
node.js: bare Carriage Returns.
Git cannot handle those, and what is worse: Git's remedy against
CVE-2020-5260 does not catch when credential helpers are used that
interpret bare Carriage Returns as newlines.
Git Credential Manager addressed this as CVE-2024-50338, but other
credential helpers may still be vulnerable. So let's not only disallow
Line Feed characters as part of the values in the credential protocol,
but also disallow Carriage Return characters.
In the unlikely event that a credential helper relies on Carriage
Returns in the protocol, introduce an escape hatch via the
`credential.protectProtocol` config setting.
This addresses CVE-2024-52006.

When asking the user interactively for credentials, we want to avoid
misleading them e.g. via control sequences that pretend that the URL
targets a trusted host when it does not.
While Git learned, over the course of the preceding commits, to disallow
URLs containing URL-encoded control characters by default, credential
helpers are still allowed to specify values very freely (apart from Line
Feed and NUL characters, anything is allowed), and this would allow,
say, a username containing control characters to be specified that would
then be displayed in the interactive terminal prompt asking the user for
the password, potentially sending those control characters directly to
the terminal. This is undesirable because control characters can be used
to mislead users to divulge secret information to untrusted sites.
To prevent such an attack vector, let's add a `git_prompt()` that forces
the displayed text to be sanitized, i.e. displaying question marks
instead of control characters.
Note: While this commit's diff changes a lot of `user@host` strings to
`user%40host`, which may look suspicious on the surface, there is a good
reason for that: this string specifies a user name, not a
<username>@<hostname> combination! In the context of t5541, the actual
combination looks like this: `user%40@127.0.0.1:5541`. Therefore, these
string replacements document a net improvement introduced by this
commit, as `user@host@127.0.0.1` could have left readers wondering where
the user name ends and where the host name begins.

Earlier we stopped using the tree of HEAD as the default source of
attributes in a bare repository, but failed to document it. This
has been corrected.
* jc/no-default-attr-tree-in-bare:

When the user adds to "git rebase -i" instruction to "pick" a merge
commit, the error experience is not pleasant. Such an error is now
caught earlier in the process that parses the todo list.

rebase -i: improve error message when picking merge
rebase -i: pass struct replay_opts to parse_insn_line()
The safe.directory configuration knob has been updated to
optionally allow leading path matches.

A scheduled "git maintenance" job is expected to work on all
repositories it knows about, but it stopped at the first one that
errored out. Now it keeps going.
* js/for-each-repo-keep-going:
maintenance: running maintenance should not stop on errors
for-each-repo: optionally keep going on an error
Make it clear that the interactive.singleKey configuration option is
disabled by default, using rather subtle wording that avoids an
emphasis on the actual default value. This should eliminate any
associated doubts.
While there, touch up the remaining wording of the description a bit.

51441e64 (stop using HEAD for attributes in bare repository by
default, 2024-05-03) has addressed a recent performance regression
by partially reverting a topic that was merged at 26dd307c (Merge
branch 'jc/attr-tree-config', 2023-10-30). But it forgot to update
the documentation to remove the mention of a special case in bare
repositories.

The only todo commands that accept a merge commit are "merge" and
"reset". All the other commands like "pick" or "reword" fail when they
try to pick a a merge commit and print the message
error: commit abc123 is a merge but no -m option was given.
followed by a hint about the command being rescheduled. This message is
designed to help the user when they cherry-pick a merge and forget to
pass "-m". For users who are rebasing the message is confusing as there
is no way for rebase to cherry-pick the merge.
Improve the user experience by detecting the error and printing some
advice on how to fix it when the todo list is parsed rather than waiting
for the "pick" command to fail. The advice recommends "merge" rather
than "exec git cherry-pick -m ..." on the assumption that cherry-picking
merges is relatively rare and it is more likely that the user chose
"pick" by a mistake.
It would be possible to support cherry-picking merges by allowing the
user to pass "-m" to "pick" commands but that adds complexity to do
something that can already be achieved with
exec git cherry-pick -m1 abc123

When safe.directory was introduced in v2.30.3 timeframe, 8959555c
(setup_git_directory(): add an owner check for the top-level
directory, 2022-03-02), it only allowed specific opt-out
directories. Immediately after an embargoed release that included
the change, 0f85c4a3 (setup: opt-out of check with safe.directory=*,
2022-04-13) was done as a response to loosen the check so that a
single '*' can be used to say "I trust all repositories" for folks
who host too many repositories to list individually.
Let's further loosen the check to allow people to say "everything
under this hierarchy is deemed safe" by specifying such a leading
directory with "/*" appended to it.
