[PATCH] mergetool--lib: make (g)vimdiff workable under Windows

[PATCH] mergetool--lib: make (g)vimdiff workable under Windows

[David Aguilar]

From: Markus Heidelberg <markus.heidelberg@web.de>

Under Windows vimdiff and gvimdiff are not available as symbolic links,
but as batch files vimdiff.bat and gvimdiff.bat. These files weren't
found by 'type vimdiff' which led to the following error:

The merge tool vimdiff is not available as 'vimdiff'

Even if they were found, it wouldn't work to invoke these batch files
from git-mergetool.

To solve this, use vim and gvim (vim.exe and gvim.exe) and pass the -d
command line switch over to them.

Markus' last patch rebased.

This patch goes on top of the current difftool/mergetool patches from David.
This is 'da/difftool' in the current 'pu' and in addition:
[PATCH] mergetool-lib: refactor run_mergetool and check_unchanged
[PATCH] mergetool-lib: specialize opendiff options when in diff mode
