parse-options-cb: implement parse_opt_passthru()

Browse Source 
Certain git commands, such as git-pull, are simply wrappers around other
git commands like git-fetch, git-merge and git-rebase. As such, these
wrapper commands will typically need to "pass through" command-line
options of the commands they wrap.

Implement the parse_opt_passthru() parse-options callback, which will
reconstruct the command-line option into an char* string, such that it
can be passed to another git command.
