histedit: make comment part of the file describing rules as translatable
"i18n.gettext()" invocation for "editcomment" itself should have
little impact for whole initialization cost of histedit, because it is
already invoked for initialization of the command table entry.
'\n\n' has to be added to the text being edited separately from
"editcomment", because leading 'line feed' characters are not exported
to "hg.pot" file correctly.

In the merge below, the file "foo" has the same contents in both
parents, but if we look at the file-level history, we'll notice that
the version in p1 is an ancestor of the version in p2. This test makes
sure that we'll use the version from p2 in the manifest of the merge
revision.
