[PATCH 00/25] completion: add missing diff options

["Philippe Blain via GitGitGadget" <gitgitgadget@gmail.com>]

This series adds missing diff options to the Bash completion script.
Completion often serves as a discovery mechanism for options, so it is
beneficial to users if all options are offered by the completion script.

The list of missing options was generated by:

 1. Extracting all diff options from the documentation:
    
    git grep -h --no-column --only-match -e ^--[a-z][a-z-]*
    Documentation/diff-options.txt
    | sort -u > diff-options.txt

 2. Searching for each option in the completion script and visually checking
    which one was missing:
    
    while read p; do echo --- $p ---; echo; git grep --color -p -e $p
    upstream/master contrib/completion/git-completion.bash done <
    diff-options.txt

The only options I left out are --skip-to and --rotate-to, since I agree
with their documentation: they are probably not very useful outside of their
use in 'git difftool'.

Cheers,

Philippe.
