Is there anything unimportant? A rhetorical question, of course.
The quite casual and natural use of "to rebase" as a verb in the
first sentence contradicts with what the parenthetical "its odd
name" comment says. Perhaps drop everything after "(which..."?
i.e.
The `--onto` option allows to rebase a range of commits onto
a different base commit. Port the support for the option to
the C re-implementation.

We usually do not say "This commit does X", or (worse) "I do X in
this commit". Instead, order the codebase to be like so, e.g.
"Support command line options by adding a call to parse_options();
later commits will add more options by building on top." or
something like that.

OK. This correctly calls the parser after repository setup.
