util: factor out shellsplit() function It turned out to be more than the simple posix=True|False flag, so let's introduce a platform function. I also made it py3 ready.

diff: do not split function name if character encoding is unknown Only ASCII characters can be split reliably at any byte positions, so let's just leave long multi-byte sequence long. It's probably less bad than putting an invalid byte sequence into a diff. This doesn't try to split the first ASCII slice from multi-byte sequence because a combining character may follow.

histedit: use repo.revs() instead of repo.set() where revisions are needed Follows up 72da480db4a5. This is just a micro optimization, but looks slightly nicer.

acl: replace bare getpass.getuser() by platform function Follows up dbadf28d4db0. bytestr() shouldn't be applied here because getuser() isn't guaranteed to be all in ASCII. This change means GetUserNameA() is used on Windows, but that's probably better than trying to get the current user name in UNIX way.

context: remove basectx.__int__ (API) basectx is the only type in the repo having __int__ implemented. This magic method can result in unexpected coercion. Furthermore, having it implemented is wrong for some contexts, since rev() may return None in some cases. Previous commits removed known cases in core where contexts are coerced to integers. So let's delete basectx.__int__. This commit is a bit dangerous. While the test suite passes, there are likely still some callers in core that rely on __int__ that don't have test coverage. An alternative would be to issue a deprecation warning and let this bake for a few releases. .. api:: context.basectx no longer implements __int__. Context instances will no longer cast to ints. Consumers should call ``ctx.rev()`` instead. Differential Revision: https://phab.mercurial-scm.org/D2433

histedit: resolve revs before evaluating %ld revset We want to stop relying on basectx.__int__. That means we can't use the %ld revset operator with an iterable of contexts. So we expand an iterable of contexts into a list of revs before calling into the revset. Perhaps it would be worthwhile to add a revset format operator that recognizes context instances so we can just pass contexts as revset arguments?

templatekw: use ctx.rev() instead of casting context to int basectx has __int__ implemented. Per mailing list discussion with Yuya, we don't like having this implemented because it is too much magic and in some cases rev() will return None, which isn't an int. So convert a `'%d' % ctx` to ctx.rev() instead. Differential Revision: https://phab.mercurial-scm.org/D2423
