Documentation options: Code or not?

[Michael Lyons <git@michael.lyo.nz>]

I noticed that git-scm.com's documentation for `git-am` has a different color 
for the rerere options than it does for the other ones. Those options are 
imported from rerere-options.adoc, which adds code backticks to the keys:

`--rerere-autoupdate`::
`--no-rerere-autoupdate`::
	After the rerere mechanism reuses a recorded resolution...

I started a quick commit to drop the backticks from rerere-options, but then 
sampled a few other doc pages. Some use backticks (git-merge, git-repo), and 
some don't (git-prune, git-name-rev). Is there a preferred style? Would an 
update to make them consistent be useful or just annoying?

Thank you,
Michael
