completion: improvements for git stash

Previous round was at <[email protected]>.

Thanks Junio for your input on the previous round.

This round drops what was 1/3 in the previous round. We keep completing the options for 'git stash save', so calling the variable 'save_opts' and defining what would be 'push_opts' as 'save_opts' + '--message' makes sense.

2/3 (now 1/2) was mostly rewritten. We now no longer suggest 'save' in 'git stash <tab>', complete 'git stash s<tab>' will complete to 'git stash show', but 'git stash sa<tab>' (or longer) will keep completing to 'git stash save', as the user most likely already knows about 'git stash save', and wanted to type that. We also keep completing the options for 'git stash save' on 'git stash save --<tab>'.

3/3 (now 2/2) stays the same as in the previous round.

I didn't find a good way to implement "reluctant completion" (I'm also by no means an expert in bash completion, so there may well be a way I couldn't find by googl'ing around), so I left that out of this series.

I don't think it's strictly necessary for the deprecation either, as we can just print a warning message when the user actually uses 'git stash save' at some point, which would make a message printed when using the completion redundant anyway. I feel like that warning message is not something we're quite ready for yet and I'd rather wait a few more releases before doing that though.

Thomas Gummerer (2):
completion: stop showing 'save' for stash by default
completion: make stash -p and alias for stash push -p
