Hi,
The process of converting all the manpages to the `synopsis` style
is ongoing.
The aim is to use the "smart" synopsis format (using backticks for
inline code), for which a parser makes the special formatting for
keywords, placeholders and grammatical marks.
I took the path of converting the pages in the order of appearance
on git-scm.com.
For a good idea of the final rendering, you can check git-commit or
git-add. I'm always open to a helping hand in this task, with enough
communication to not duplicate work. To be honest, the conversion process
is far from being completely formalized, so you may need a couple
iterations before the rules are completely clear.
Let me know if you are interested.
