Fix various issues of SYNOPSIS and -h output syntax where: * Options such as --force were missing entirely * ...or the short option, such as -f * We said "opts" or "options", but could instead enumerate the (small) set of supported options * Options that were missing entirely (ls-remote's --sort=<key>) As we can specify "--sort" multiple times (it's backed by a string-list" it should really be "[(--sort=<key>)...]", which is what "git for-each-ref" lists it as, but let's leave that issue for a subsequent cleanup, and stop at making these consistent. Other "ref-filter.h" users share the same issue, e.g. "git-branch.txt". * For "verify-tag" and "verify-commit" we were missing the "--raw" option.
