run-tests: also send a message in the Keyboard interrupt case
The next patch will do something equivalent, so lets do the change in an
independant changeset first in case we need to bisect something in the future.
revlog: use appropriate format char for int ("i" instead of "I")
From https://docs.python.org/3.8/c-api/arg.html#numbers :
i (int) [int]
Convert a Python integer to a plain C int.
I (int) [unsigned int]
Convert a Python integer to a C unsigned int, without overflow checking.
revlog: use %d to format int instead of %lu (
issue6565)
The issue says gcc warns that the data types don't match. I couldn't reproduce
the warning locally for some reason, but this patch shouldn't break things.
Maybe %lu was simply a copy-paste error from
6b1eae313b2f
(https://phab.mercurial-scm.org/D10625).
rhg: correctly handle the case where diffs are encoded relative to nullrev
returning a valid entry for nullrev fix chain that delta against nullrev.
