Call clear_pathspec() at the end of various functions that work with
and allocate a "struct pathspec".

Move this way above, perhaps next to where "int i;" is declared, or
replace the blank before where module_list_options[] is declared
with this line.

The same comment applies to changes to module_foreach() and
status_submodule_cb() in this patch.  The change to
absorb_git_dirs() gets it right.

Thanks.
