So I wonder whether it wouldn't be worthwile to make their job easier
(and thereby avoid bugs like the one described above) by handling async
and sync processes alike in this respect. The condition for this to
work is that backend functions don't expect point to be preserved,
except, of course, if it is actually their purpose to compute point
(like for vc-git-show-log-entry).
I like the idea, but FWIW the patch breaks diff-hl-revert-hunk (diff-hl
is in GNU ELPA). Haven't investigated it further yet.
And the particular bug you've described, naturally, can also be fixed by
making vc-hg-print-log asynchronous:
