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.
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
