log: map None rev to wdirrev when filtering revisions with --line-range
When 'hg log -f --line-range <file>,<range>' is invoked with <range>
containing uncommitted changes, the command crashes on Python 3 as
follows:
[...]
File "/usr/lib/python3/dist-packages/mercurial/commands.py", line 4725, in log
revs, differ = logcmdutil.getlinerangerevs(repo, revs, opts)
File "/usr/lib/python3/dist-packages/mercurial/logcmdutil.py", line 933, in getlinerangerevs
if rev not in userrevs:
File "/usr/lib/python3/dist-packages/mercurial/smartset.py", line 969, in __contains__
if l < x:
TypeError: '<' not supported between instances of 'int' and 'NoneType'
The None value is because requested line range has uncommitted changes,
so 'rev' is the working directory revision. This only occurs in Python 3
as Python 2 allows comparing None with int.
As suggested by Yuya Nishihara, mapping None to node.wdirrev resolves
the issue and also make the '--line-range' option properly work with -r
'wdir()'. We add extra tests for non-regression and to illustrate
handling of 'wdir()'.
