Yeah, shortly after I sent the above message there came additional
changesets, with a couple of additional missing versions ; then "hg
fetch" refused to merge because there were several outlying heads in
the default branch — so I merged them back manualy as best I could
with each other and with my (few) local changes, and "hg merge" each
time displayed a 3-way vimdiff for src/version.c — to make sure that
the merge took the right copy I made all three buffers equal to what I
thought was wanted — and now Vim says "Included patches: 1-1778". The
latest "hg fetch" pulled and merged without requiring my intervention
so I assume that my clone is OK again.
Oh, BTW : src/version.o has a line for patch 1778 but AFAICT there is
no tag v9.0.1778 known to Mercurial.
Best regards,
Tony.
