py3: use python3 hg in test-py3-commands.t at places where py2 hg was used
This patch fixes my mistakes where I added test in test-py3-commands.t as
`hg ...` where I forgot hg here refers to Python 2 mercurial.
test-dirstate-race: back out changeset

This is non-deterministic. In any case, I switched to using
debugrebuilddirstate in my WIP patches, which makes this moot.
revset: fix order of first/last members in compound expression (BC)
Suppose len(subset) >> len(ls) in common cases, 'subset & ls' should be
avoided whenever possible.
revset: filter first/last members by __and__ operation
This replaces 'if y in subset' with '& subset'. first(null) and last(wdir())
are fixed thanks to fullreposet.__and__.
This also revealed that first() and last() don't follow the order of the
input set. 'ls & subset' is valid only if the ordering requirement is 'define'
or 'any'.
No performance regression observed:
revset #0: limit(0:9999, 100, 9000)
0) 0.001164
1) 0.001135
revset #2: 9000 & limit(0:9999, 100, 9000)
0) 0.001224
1) 0.001181
revset #3: last(0:9999, 100)
0) 0.000237
1) 0.000199
revset: reject negative number to select first/last n members
Negative 'lim' doesn't make sense here, and it makes things complicated
when using list[:lim].
revset: fix order of last() n members where n > 1 (BC)
last() is implemented using a reversed iterator, so the result should be
reversed again.
I've marked this as BC since it's quite old bug seen in 3.0. The first bad
revision is
4849f574aa24 "revset: changed last implementation to use lazy
classes."
debugrevspec: add option to suppress list of computed revisions
Test will be added later.
debugrevspec: add option to print representation of smartset object
It's possible by -v, but -v also prints a parsed tree. Test will be added
later.
help: correct description of "glob:foo/*" matching
Unlike what the description says, it does not match recursively. Also
add an example of "glob:foo/**" (which does match recursively).
bookmarks: make sure we close the bookmark file after reading
We previously lacked an explicit close of the bookmark file.
