help: populate template functions via docstrings We do this for revsets, template keywrods, and template filters. Now we do it for template functions as well.

templater: add consistent docstrings to functions The content of "hg help templating" is largely derived from docstrings on functions providing functionality. Template functions are the long holdout. Prepare for generating them dynamically by defining docstrings for all template functions. There are numerous ways these docs could be improved. Right now, the help output simply shows function names and arguments. So literally any accurate data is better than what is there now.

changeset_printer: hide manifest node for workingctx Because workingctx has no manifest, it makes sense to hide "manifest:" row completely.

changeset_printer: display p1rev:p1node with "+" suffix for workingctx Still templater can't handle workingctx, which will be fixed later.

changeset_printer: handle workingctx in _meaningful_parentrevs()

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: 1054af7d04aef64378d69a0496b45cdbf6a0bef2 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. http://selenic.com/repo/hg/rev/606a3bf82e30?style=monoblue

merge with stable

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 80f2b63dd83a.
