util: clarify purpose of MBTextWrapper class
It's easy to get confused and scared of an Unicode monster when
skimming through this code: document that this is really just
about column-counting.
run-test: fixed wrong parenthesis
Fixed wrong placement of end parenthesis, from
b911cb80c671
graphmod: safer code when a changeset has two identical parents
While this situation should never under normal use, some real
life repos sometimes contain such changesets (older hg versions,
broken rebases, etc...)
hgweb was displaying an "Internal error" in this case, and graphlog
displayed a redundant branch all the way to null: it does not cost us
much to just ignore this extra parent when constructing the DAG.
revlog: fix descendants() if nullrev is in revs
We were not returning the correct result if nullrev was in revs, as we
are checking parent(currentrev) != nullrev before yielding currentrev
test-convert-hg-startrev was wrong: if we start converting from rev -1 and
onwards, all the descendants of -1 (full repo) should be converted.
mq: use sets instead of lists for speed
The code eventually converts data through sets to ensure unicity:
do it earlier to allow faster __contains__ lookups and avoid
`del l[l.index(x)]` kind of code.
