Document generation by runrst in "doc" directory may succeed silently, even though there is the translated message missing tail '::'. In this case, it uses "<blockquote>" instead of "<pre>" to surround succeeding text block unexpectedly in generated HTML file. This patch adds the checker to check equality of tail '::'-ness between msgid and msgstr. To detect also msgstr unexpectedly ending with '::', this checker doesn't have matching regexp against msgid, and is applied on all msgid/msgstr pairs. This checker is categorized as "warning" level, because problem detected by this is not so serious for usual Mercurial usage.
