cext: correct the argument handling of `b85encode()`
The type stub indicated that this argument is `Optional`, which implies None is
allowed. I don't see in the documentation where that's the case for `i`[1], and
trying it in `hg debugshell` resulted in the method failing with a TypeError. I
guess it was typed as an `int` argument because the `p` format unit wasn't added
until Python 3.3[2].
In any event, 2 clients in core (`pvec` and `obsolete`) call this with no
argument supplied, and `mdiff` calls it with True. So I guess we've avoided the
None arg case, and when no arg is supplied, it defaults to the 0 initialization
of the `pad` variable in C. Since the `p` format unit accepts both `int` and
None, as well as `bool`, I'm not bothering to bump the module version- this code
is more permissive than it was, in addition to being more correct.
Interestingly, when I first imported the `cext` and `pure` methods in the same
manner as the previous commit, it dropped the `Optional` part of the argument
type when generating `util.pyi`. No idea why.

#!/bin/bash # # produces two repositories with different common and missing subsets # # $ discovery-helper.sh REPO NBHEADS DEPT # # The Goal is to produce two repositories with some common part and some # exclusive part on each side. Provide a source repository REPO, it will # produce two repositories REPO-left and REPO-right. # # Each repository will be missing some revisions exclusive to NBHEADS of the # repo topological heads. These heads and revisions exclusive to them (up to # DEPTH depth) are stripped. # # The "left" repository will use the NBHEADS first heads (sorted by # description). The "right" use the last NBHEADS one. # # To find out how many topological heads a repo has, use: # # $ hg heads -t -T '{rev}\n' | wc -l # # Example: # # The `pypy-2018-09-01` repository has 192 heads.
