While parsing the command-line arguments, git-pull stops parsing at the
first unrecognized option, assuming that any subsequent options are for
git-fetch, and can thus be kept in the shell's positional parameters
list, so that it can be passed to git-fetch via the expansion of "$@".
However, certain functions in git-pull assume that the positional
parameters do not contain any options:
* error_on_no_merge_candidates() uses the number of positional
parameters to determine which error message to print out, and will
thus print the wrong message if git-fetch's options are passed in as
well.
* the call to get_remote_merge_branch() assumes that the positional
parameters only contains the optional repo and refspecs, and will
thus silently fail if git-fetch's options are passed in as well.
* --dry-run is a valid git-fetch option, but if provided after any
git-fetch options, it is not recognized by git-pull and thus git-pull
will continue to run the merge or rebase.
Fix these bugs by teaching git-pull to parse git-fetch's options as
well. Add tests to prevent regressions.

To enable unambiguous parsing of abbreviated options, bundled short
options, separate form options and to provide consistent usage help, use
git-rev-parse --parseopt for option parsing. This allows the option parsing
code to be simplified.
