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.
This removes the limitation where git-fetch's options have to come after
git-merge's and git-rebase's options on the command line. Update the
documentation to reflect this.

Notes:
Improve git-pull's option parsing
Previous versions:
[v1] http://thread.gmane.org/gmane.comp.version-control.git/269249
This patch series is based on pt/pull-tests.
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 "$ <at>
".
However, certain functions in git-pull assume that the positional
parameters do not contain any options. Fix this by making git-pull
handle git-fetch's options as well at the option parsing stage.
With this change in place, we can move on to migrate git-pull to use
git-rev-parse --parseopt such that its option parsing is consistent with
the other git commands.
I believe this is the last required behavior change for my rewrite of
git-pull.sh to C.
v2
* Initialize variables to prevent them from being set in the command
line.
* Update the documentation as well.
