dirstate-tree: Ignore FIFOs etc. in the status algorithm If a filesystem directory contains anything that is not: * a "normal" file * a symbolic link * or a directory … act as if that directory entry was not there. For example, if that path was previously a tracked file, mark it as deleted or removed. Differential Revision: https://phab.mercurial-scm.org/D10548
