** [bugs:#380] manpage writer does not add space after .B**

I'm using sphinx-argparse to generate a man page from an argparse object.
The generated man page has no spaces after .B inserted.
This causes `--option` to show up as `-option` or `-o` as `o` in the manual.

I think the cause of this problem is in docutils because adding a space after `'.B'` at
https://github.com/docutils-mirror/docutils/blob/e88c5fb08d5cdfa8b4ac1020dd6f7177778d5990/docutils/writers/manpage.py#L887
fixed the problem for me.
(`'.B' -> '.B '`)

I've created a reproducer using sphinx-argparse.
This requires (at least) sphinx-argparse, sphinx and docutils.
