git-annex/doc/todo/mdwn2man:_make_backticks_bold.mdwn

The traditionnal way of marking commandline flags in a manpage is with a `.B` (for Bold, I guess). It doesn't seem to be used by mdwn2man, which makes the manpage look a little more dull than it could.

The following patch makes those options come out more obviously:

[[!format diff """

I tested it against the git-annex manpage and it seems to work well. --[[anarcat]]
