revset: added sort methods to generatorsets
Method needed to propagate sort calls amongst lazy structures.
The generated list (stored in the object) is sorted.
If the generated list did not contain all elements from the generator, we
take care of that before sorting the list.
$ "$TESTDIR/hghave" execbit || exit 80
$ hg init
$ echo a > a
$ hg ci -Am'not executable'
adding a
$ chmod +x a
$ hg ci -m'executable'
$ hg id

Make sure we notice the change of mode if the cached size == -1:
$ hg rm a
$ hg revert -r 0 a
$ hg debugstate
n 0 -1 unset a
$ hg status
M a
$ hg up 0
1 files updated, 0 files merged, 0 files removed, 0 files unresolved

$ test -x a && echo executable -- bad || echo not executable -- good
not executable -- good
