Merge branch 'jc/clear-pathspec'

We usually call a function that clears the contents a data structure X without freeing the structure itself clear_X(), and call a function that does clear_X() and also frees it free_X(). free_pathspec() function has been renamed to clear_pathspec() to avoid confusion. * jc/clear-pathspec: pathspec: rename free_pathspec() to clear_pathspec()
