build: fix hgrc manpage building with docutils 0.9
Since docutils 0.9, `roman` module has been moved from module directory root
(i.e. `site-packages/roman.py`) to `docutils.utils` module. Therefore `import
roman` statement should be wrapped in `try: ... except ImportError: ...` block
to handle importing correctly.
alias: inherit command optionalrepo flag (
issue3298)
Commands working without a repository, like "init", are listed in
commands.norepo. Commands optionally using a repository, like "showconfig", are
listed in commands.optionalrepo. Command aliases were inheriting the former but
not the latter.
