Hi,

Git's bash completion script offers possible arguments to some
options, e.g. it lists pretty formats after 'git log --pretty=<TAB>',
merge tools after 'git mergetool --tool=<TAB>', refs after 'git commit
--reuse-message=<TAB>', etc.

On a three day old ubuntu 10.10 install these don't work anymore; the
completion script offers the list of files in all those cases.

After a bit of investigation I found that when I press TAB after 'git
log --pretty=', then ${COMP_WORDS[COMP_CWORD-1]} contains '--pretty'
and ${COMP_WORDS[COMP_CWORD]} contains "=".  Weird.

Then I remembered that we had some COMP_WORDBREAKS issues in the past
(db8a9ff, bash completion: Resolve git show ref:path<tab> losing ref:
portion, 2008-07-15)).  So I looked at my $COMP_WORDBREAKS, but didn't
see anything suspicious (it contains "'><=;|&(: ).  Removing the '='
makes the listing after 'git log --pretty=' work, but breaks many
other things badly.

I don't have any ideas what could possibly be wrong here (but it's too
late here for any bright ideas anyway...).  Could someone confirm or
deny this behaviour on ubuntu 10.10?


Thanks,
Gábor

Confirmed.  Completion works properly on OS X, but fails on Ubuntu 10.10

OS X 10.6.4:
  bash: 3.2.48
  git:  1.7.3.1.209.g52408 (next + my t/gitweb-lib patch)
  output:
$ git log --pretty=<tab><tab>
email     full      medium    raw       
format:   fuller    oneline   short  

Ubuntu 10.10:
  bash: 4.1.5
  git:  1.7.1 (from apt)
  output:
$ git log --pretty=<tab><tab>
.bash/               .irbrc
.bash_history        .less
.bash_logout         .local/
.bash_profile        Music/
--More--

My guess is that it has to do with Bash 4, the equal sign must be seen
as a new word. I'm running Ubuntu 10.04 and have the same problem.
I fixed the problem locally, I just don't know if that works on Bash 3
and I doubt it will work on Bash 3.

I changed the script only for git log, not other commands yet, like 
git am --whitespace=<tab><tab>

Looks like you're right. I'm running bash 4.1.7 on OS X and it's broken here.
