log: make -fr show complete history from the given revs
Right now it's very obtuse to show the history of a particular rev (hg log -r
'reverse(::foo)'). This changes the -f option to make it follow history for the
revs specified by -r.
The current -f -r behavior is to limit the result of -r to only the
commits that are ancestors of the current working copy. Changing this
is a bit of a BC break, but the old behavior is A) rare, B) easy to
emulate (& ::.), and C) currently undefined. The new behavior is
frequently requested enough that I think the change is worth it.
"""test behavior of propertycache and unfiltered propertycache
The repoview overlay is quite complex. We test the behavior of
property cache of both localrepo and repoview to prevent
regression."""
