In particular, it can get called with four arguments if you happen to
be referring to a repo using the ssh:// scheme with a non-default port
number.

Commit 1b77d83cab 'setup_git_directory_gently_1(): resolve symlinks
in ceiling paths' changed the setup code to resolve symlinks in the
entries in GIT_CEILING_DIRECTORIES. Because those entries are
compared textually to the symlink-resolved current directory, an
entry in GIT_CEILING_DIRECTORIES that contained a symlink would have
no effect. It was known that this could cause performance problems
if the symlink resolution *itself* touched slow filesystems, but it
was thought that such use cases would be unlikely. The intention of
the earlier change was to deal with a case when the user has this:
GIT_CEILING_DIRECTORIES=/home/gitster
but in reality, /home/gitster is a symbolic link to somewhere else,
e.g. /net/machine/home4/gitster. A textual comparison between the
specified value /home/gitster and the location getcwd(3) returns
would not help us, but readlink("/home/gitster") would still be
fast.
After this change was released, Anders Kaseorg <andersk@mit.edu>
reported:
> [...] my computer has been acting so slow when I’m not connected to
> the network. I put various network filesystem paths in
> $GIT_CEILING_DIRECTORIES, such as
> /afs/athena.mit.edu/user/a/n/andersk (to avoid hitting its parents

> volumes). Now when I’m not connected to the network, every

To allow users to work around this problem, give them a mechanism to
turn off symlink resolution in GIT_CEILING_DIRECTORIES entries. All
the entries that follow an empty entry will not be checked for symbolic
links and used literally in comparison. E.g. with these:
GIT_CEILING_DIRECTORIES=:/foo/bar:/xyzzy or
GIT_CEILING_DIRECTORIES=/foo/bar::/xyzzy
we will not readlink("/xyzzy") because it comes after an empty entry.
With the former (but not with the latter), "/foo/bar" comes after an
empty entry, and we will not readlink it, either.

The old Git version where it appeared is now useful only to historians,
not to normal users. Also, the text was mentioning only the per-repo
config file, but this is a good place to teach that customization can
also be made per-user.
While at it, remove a now-defunct e-mail from an example.

When attempting to read the XDG-style $HOME/.config/git/config and
finding that $HOME/.config/git is a file, we gave a wrong error
message, instead of treating the case as "a custom config file does
not exist there" and moving on.
* jn/warn-on-inaccessible-loosen:
config: exit on error accessing any config file
doc: advertise GIT_CONFIG_NOSYSTEM
config: treat user and xdg config permission problems as errors
config, gitignore: failure to access with ENOTDIR is ok

We earlier removed a link to list of contributors that pointed to a
defunct page; let's use a working one from Ohloh.net to replace it
instead.

Unlike other environment variables (e.g. GIT_WORK_TREE, GIT_NAMESPACE),
the Documentation/git.txt file did not mention that the GIT_DIR
environment variable can also be set using the --git-dir command line
option.

The linked page has not been showing the promised "more complete
list" for more than 6 months by now, and nobody has resurrected
the list there nor elsewhere since then.

On a multiuser system where mortals do not have write access to /etc,
the GIT_CONFIG_NOSYSTEM variable is the best tool we have to keep
getting work done when a syntax error or other problem renders
/etc/gitconfig buggy, until the sysadmin sorts the problem out.
Noticed while experimenting with teaching git to error out when
/etc/gitconfig is unreadable.

The second paragraph in the git(1) description section were meant to
guide people who are not ready to dive into this page away from here.
Referring migrating CVS users to another page before they get
acquainted with Git was somewhat out of place. Move the reference to
the "FURTHER DOCUMENTATION" section and push that section down.
