Merge branch 'nd/magic-pathspec'

Use "struct pathspec" interface in more places, instead of array of
characters, the latter of which cannot express magic pathspecs
(e.g. ":(icase)makefile" that matches both Makefile and makefile).

* nd/magic-pathspec:
add: lift the pathspec magic restriction on "add -p"
pathspec: catch prepending :(prefix) on pathspec with short magic
