The merge tools vimdiff2, vimdiff3, gvimdiff2, gvimdiff3 and bc3 are all
variants of the main tools vimdiff and bc. They are implemented in the
main and a one-liner script that just sources it exist for each.
This patch allows variants ending in [0-9] to be correctly wired without
the need for such one-liners, so instead of 5 scripts, only 1 (gvimdiff)
is needed.
