Match a pathspec against the working directory of a repository.

This matches the pathspec against the current files in the working directory of the repository. It is an error to invoke this on a bare repo. This handles git ignores (i.e. ignored files will not be considered to match the pathspec unless the file is tracked in the index).

If out is not NULL, this returns a git_patchspec_match_list. That contains the list of all matched filenames (unless you pass the GIT_PATHSPEC_FAILURES_ONLY flag) and may also contain the list of pathspecs with no match (if you used the GIT_PATHSPEC_FIND_FAILURES flag). You must call git_pathspec_match_list_free() on this object.
