[PATCH] completion: fix issues with COMP_WORDBREAKS

[Felipe Contreras]

The situation regarding COMP_WORDBREAKS has changed through time, but
right now due to changes in bash 4 we are using _get_comp_words_by_ref
and there's no need to mess directly with COMP_WORDBREAKS any more.

In fact if COMP_WORDBREAKS doesn't contain a colon the completion gets
all messed up. For example:

 git push origin master:<TAB>
 git diff master:<TAB>

The "master:" prefix would be added again, unnecessarily.

Thanks.  Yeah, that sounds broken.

Unfortunately the patch introduces a regression: if after loading the
completion script I set COMP_WORDBREAKS not to contain a colon, then
with the current completion script

	git show HEAD:Docu<TAB>

completes fine, but with the patched completion script it seems to
get confused and strips off the HEAD.

Ideas?
Jonathan

I don't understand, I tested this and it was working fine, but not any more =/

Maybe I was testing on zsh.

I guess this should be dropped then.

Cheers.
