[PATCH] Documentation/git-clone: improve description for submodule recursing




There have been a few complaints on the mailing list that git-clone doesn't
respect the `submodule.recurse` setting, which every other command (that
potentially knows how to deal with submodules) respects.  In case of clone
this is not beneficial to respect as the user may not want to obtain all
submodules (assuming a pathspec of '.').

Improve the documentation such that the pathspec is mentioned in the
synopsis to alleviate the confusion around the submodule recursion flag
in git-clone.

While at it clarify that the option can be given multiple times for complex\
pathspecs.
