scmutil: add function to help handling workingctx in arithmetic operation
It's unfortunate that workingctx revision is None, which doesn't work well in
arithmetic operation or comparison. This function is trivial but will be used
in several places.
tests: handle deleted .hg directory (git 2.2.0 and higher) (
issue4585)
In git 2.2.0 and higher, removing files and directories is changed:
removing an object that does not exist returns success rather than failure.
As a result, even though .hg/hgrc does not exist, success is returned
and the .hg/ directory is removed.
To handle this correctly, use 'rm -rf' to allow successful removing
for all git versions.
The exact changeset where this was introduced in git:

wrapper.c: remove/unlink_or_warn: simplify, treat ENOENT as success
hgweb: resurrect <span> tag on diffline to fix rendering in monoblue style
It was removed at
606a3bf82e30 as a useless tag, but it is necessary to
apply "div.diff pre span" style.

encoding: use parsers.asciiupper when available
This is used on Windows and Cygwin, and the gains from this are expected to be
similar to what was seen in
