Re: [PATCH] Speed up bash completion loading

I was under the impression that setting variables during completion 
meant they were lost at the end of the completion cycle. So to be safe I 
put a 'sleep 5' in __git_list_porcelain_commands() and it only stalled 
me once :-)

I see a small problem, but it can be fixed in another patch. git merge 
-s <TAB><TAB> the first time when you're not in a git directory will 
make git merge -s <TAB><TAB> after never complete correctly even in a 
git directory. I guess this become more serious if git isn't in your 
path initially and you do git <TAB><TAB> and then git becomes part of 
your path and you try again. Here you lose porcelain completion. This is 
probably never going to happen though, right?

Plus it seems that __git_all_commands is computed twice if I git 
<TAB><TAB> and then git help <TAB><TAB> after. Can that be avoided?

Squashing this on top fixes the two typos you mentioned.
