procutil: make recent fix for zombies compatible with py2 The fix in ed684a82e29b (procutil: always waiting on child processes to prevent zombies with 'hg serve', 2020-05-07) works only on Python 3 because it passes a `daemon` argument to `threading.Thread()`. Python 2 requires you to assign to the `.daemon` property instead. Python 3 also seems to support that, so this patch fixes the code by unconditionally using the old form.

pycompat: fix crash when default locale is unknown Instead, fall back to the filesystem encoding if the default locale is unknown.

help: document meaning of '%' in graphlog output I added the feature in 14d0e89520a2 (graphlog: use '%' for other context in merge conflict, 2020-01-28), but I didn't think to look for documentation until today (because an internal user asked about it).

py3: fix broken man page generation, it was generating `(default: NUL*)` `bytes(default)` was producing things like `(default: \x00)` when handed non-bytes values such as `1`, `10`, or `True`. The man page generation would apparently ignore these bytes and produce man pages that had the string `(default: )`. Test Plan: - Ran `cd doc; python3 gendoc.py "hg.1.gendoc"` and grepped for bad output - Ran `make deb`, extracted the deb, manually inspected `hg.1` file.

py3: fix comparison between int and None If stop is None, the condition was always false on Python 2, as None compares smaller than ints. Therefore we make the condition false if stop is None.

py3: pass regex as bytes
