[PATCH 1/4] Support --strategy=x completion in addition to --strategy x.

["Shawn O. Pearce" <spearce@spearce.org>]

Because git-merge and git-rebase both accept -s, --strategy or --strategy=
we should recognize all three formats in the bash completion functions and
issue back all merge strategies on demand.

I also moved the prior word testing to be before the current word testing,
as the current word cannot be completed with -- if the prior word was an
option which requires a parameter, such as -s or --strategy.
