[PATCH next resend] bash completion: refactor diff options

[Thomas Rast <trast@student.ethz.ch>]

diff, log and show all take the same diff options.  Refactor them from
__git_diff and __git_log into a variable, and complete them in
__git_show too.

Signed-off-by: Thomas Rast <trast@student.ethz.ch>

Any news on this?
