Function exclude_matches_pathspec

dir.c:2264–2294

* This function tells us whether an excluded path matches a * list of "interesting" pathspecs. That is, whether a path matched * by any of the pathspecs could possibly be ignored by excluding * the specified path. This can happen if: * * 1. the path is mentioned explicitly in the pathspec * * 2. the path is a directory prefix of some element in the * pathspec */
