completion: add missing completions for log, diff, show

The bash completion script knows some options to "git log" and
"git show" only in the positive form, (e.g. "--abbrev-commit"), but not
in their negative form (e.g. "--no-abbrev-commit"). Add them.

Also, the bash completion script is missing some other options to
"git diff", and "git show" (and thus, all other commands that take
"git diff"'s options). Add them. Of note, since "--indent-heuristic" is
no longer experimental, add that too.
