help: add topic about evolution, based on text from evolve extension
I've taken the text produced by `hg help evolution` when the evolve
extension is enabled and made that available by the same command with
just hg core. Changes I've made:
* Added "(EXPERIMENTAL)" to the title. (That doesn't hide the topic
from `hg help`, though.)
* Replaced old-style `experimental.evolution=<names>` config by
new-style `experimental.evolution.<name>=true`.
* Replaces a "obsolete markers" by "obsolescence markers".
* Removed most content from "Current feature status".
When the evolve extension is enabled, its help text takes precedence.

look for python scripts that do not use /usr/bin/env
$ testrepohg files 'set:grep(r"^#!.*?python") and not grep(r"^#!/usr/bi{1}n/env python") - **/*.t'

In tests, enforce $PYTHON and *not* /usr/bin/env python or similar:
$ testrepohg files 'set:grep(r"#!.*?python") and **/*.t' \
> -X tests/test-check-execute.t \
> -X tests/test-check-format.t \
> -X tests/test-check-module-imports.t \
> -X tests/test-check-pyflakes.t \
> -X tests/test-check-shbang.t

The above exclusions are because they're looking for files that
contain Python but don't end in .py - please avoid adding more.
look for shell scripts that do not use /bin/sh
$ testrepohg files 'set:grep(r"^#!.*/bi{1}n/sh") and not grep(r"^#!/bi{1}n/sh")'
