minirst: remove "admonition" from _admonitions

The "admonition" rst primitive is split into "specific" admonitions
("attention," "caution," etc) and the "generic" admonition
("admonition"). For more, see
http://docutils.sourceforge.net/docs/ref/rst/directives.html#admonitions

The _admonitions set and keys of the _admonitiontitles dict
overlap exactly except _admonitions has an "admonition" entry.
Nowhere in Mercurial is the "admonition" admonition directive used.
Even if it were, it doesn't have a title, so it wouldn't be rendered
correctly.

So, let's remove "admonition" from the set of recognized admonition
directives.

# The test-repo is a live hg repository which may have evolution
# markers created, e.g. when a ~/.hgrc enabled evolution.
#
# Tests are run using a custom HGRCPATH, which do not
# enable evolution markers by default.
#
# If test-repo includes evolution markers, and we do not
# enable evolution markers, hg will occasionally complain
# when it notices them, which disrupts tests resulting in
# sporadic failures.
#
# Since we aren't performing any write operations on the
# test-repo, there's no harm in telling hg that we support
# evolution markers, which is what the following lines
# for the hgrc file do:
cat >> $HGRCPATH << EOF
[experimental]
evolution=createmarkers
EOF
