revset: handle wdir() in `roots()`...
revset: handle wdir() in `roots()`
This is already handled in `heads()`, and both are needed to determine if a set
is contiguous.
I'm guessing the `0 <= p` check was to try to filter out the null revision, but
it looks like that comes through in the corner case of a new repo with no
commits. But that was already the case, as shown by the tests.
Before (on a clone of hg):
$ python3.8 hg perf::revset --config extensions.perf=contrib/perf.py 'roots(all())'
! wall 0.059301 comb 0.040000 user 0.040000 sys 0.000000 (best of 100)
After:
$ python3.8 hg perf::revset --config extensions.perf=contrib/perf.py 'roots(all())'
! wall 0.059387 comb 0.060000 user 0.060000 sys 0.000000 (best of 100)
