Re: Custom git completion

An alias that uses another git subcommand (i.e. the ones that do not start
with a bang "!") seems to be handled correctly, but one of my aliases is
this:

    [alias]
	lgm = "!sh -c 'GIT_NOTES_REF=refs/notes/amlog git log \"$@\" || :' -"

Doing this is difficult, because its hard to parse that string and
do completion on it.

That is why I said it is unfair to expect completion code to do that.

  [completion]
  	lgm = log

and have `git lgm` complete using the same rules as `git log`.

I actually like that.  It matches _my_ expectation as a user to be able to
say "this subcommand has args that look like those given to 'log'".
