rhg: Reuse manifest when checking status of multiple ambiguous files When `rhg status` cannot determine whether a file is clean based on mtime and size alone, it needs to compare its contents with those found in the parent commit. Previously, rhg would find the (same) manifest of that commit again for every such file. This is lifted out of the loop and reused. Differential Revision: https://phab.mercurial-scm.org/D11411
