Nope, they were from the patch where I taught "git fetch" the
"--recurse-submodules" option and was not aware at that time that
"git pull" should just pass on almost all fetch options (the only
exceptions to that rule being -q, -v, -n and --progress). The thing
I had in mind was to later pass the same "--recurse-submodules"
option to the merge command too (when I finished implementing that
option). But when I understood later that pull handles the fetch
options in an interesting way I noticed that it would depend on the
order of options given if the "--recurse-submodules" would then be
passed to both fetch and merge or just to fetch, which will lead to
an interesting and unintuitive behavior I was not eager to expose.

So yes, I hit the strangeness of the "git pull" option parsing, but
decided to not mess it up further by adding another option to the
ones it does handle differently but play by the rules which are
used now (The other possibility would have been to document it
as a new option to "git pull", but that would have lead to the
problem I described earlier when merge will learn that option too).

So I have no strong feelings about this patch but believe it is the
right thing to do as long as "git pull" handles its options the way
it does. But looking at the confusion that option handling caused
I think it might be a worthwhile idea to overhaul it.
