revision.c: treat A...B merge bases as if manually specified
The documentation assures users that "A...B" is defined as "A B --not
$(git merge-base --all A B)". This wasn't in fact quite true, because
the calculated merge bases were not sent to add_rev_cmdline().
The main effect of this was that although
git rev-list --ancestry-path A B --not $(git merge-base --all A B)
worked, the simpler form
git rev-list --ancestry-path A...B
failed with a "no bottom commits" error.
Other potential users of bottom commits could also be affected by this
problem, if they examine revs->cmdline_info; I came across the issue in
my proposed history traversal refinements series.
So ensure that the calculated merge bases are sent to add_rev_cmdline(),
flagged with new 'whence' enum value REV_CMD_MERGE_BASE.
