git-gui: duplicated key binds?

Hi,

It looks to me like there are a lot of key binds duplicated in the git-gui source.

For instance, Ctrl/Cmd+Enter are bound in two lines: bind $ui_comm <$M1B-Key-Return> {do_commit;break} and bind . <$M1B-Key-Return> do_commit

I guess the first one is specified to work in the commit message widget. The second one is for all widgets(?).

Also, I see that some binds are with the "all" tag, while most are with just a dot as tag.

Is this a mistake (aka something I could write a patch for)? Or am I just missing something?

I propose:
- replace "bind .   " with "bind all "
- remove duplicated bind entries, if a key is bound to "all" then it
shouldn't be bound with another tag
