I have an empty .git/remotes directory. Trying to complete the name of
a remote always reports an error:
git@master:1023> git fetch <TAB>ls: invalid option -- ' '
Try `ls --help' for more information.
I have these:
alias ls='ls $LS_OPTIONS'
and
LS_OPTIONS='-N --color=tty -T 0'
I instrumented __git_remotes with set -x, which shows:
git@master:1006> git fetch <TAB>+++ __gitdir
+++ '[' -z '' ']'
+++ '[' -n '' ']'
+++ '[' -n '' ']'
+++ '[' -d .git ']'
+++ echo .git
++ local i 'IFS=
' d=.git
++ test -d .git/remotes
++ ls '-N --color=tty -T 0' -1 .git/remotes
ls: invalid option -- ' '
Try `ls --help' for more information.
...
Notice that the expansion of $LS_OPTIONS is not split at the blanks,
obviously, because $IFS does not contain a blank at that moment.
The patch below helps, but it looks like a work-around rather than a
solution. Ideas?

I've got two alternative solutions for this issue.
The first one is less intrusive: use the 'command' builtin to tell
the shell to ignore shell functions and aliases and just run the ls
command.
diff --git a/contrib/completion/git-completion.bash
b/contrib/completion/git-completion.bash
index be800e09..bcde9472 100644

for i in $(git --git-dir="$d" config --get-regexp 'remote\..*\.url' 2>/dev/null); do
i="${i#remote.}"
echo "${i/.url*/}"
But then it got me thinking... Notice how much effort we spend just
to get the list of remotes? We could just run 'git remote' directly
instead...

I prefer the second one ;)

Yuck. For normal scripts, nobody sane would define "alias" for
non-interactive environments, but because these things work in an
interactive environment, we have to protect ourselves from user
aliases. Not just "ls", but "test" we see above may misbehave X-<.

Right, however, while ls is frequently aliased (my ubuntu box has
alias ls='ls --color=auto' in /etc/skel/.bashrc by default, but that's
not an issue in this case), I think aliasing test is just crazy.
Yeah, it's possible, but if we go down that route, then we should also
worry about the [ builtin being aliased:
$ if [ -r nonexisting ] ; then echo found ; fi
$ alias [='echo using aliased ['
$ if [ -r nonexisting ] ; then echo found ; fi
using aliased [ -r nonexisting ]
found
$

Actually, we can't, because 'git remote' doesn't seem to list remotes
stored under .git/remotes. Is that intentional?
Anyway, we could still use 'git remote' to replace at least the config
query and the for loop to spare a few lines of code and a subshell.

Looks like a bug, as it seems to have been lost in translation in
211c8968 (Make git-remote a builtin, 2008-02-29).
list_remote() in git-remote.perl looks for remotes in config and in
.git/remotes/, too. The builtin implementation uses
remote.c:for_each_remote() from the start, which only looks at the
config.
