status: keep second-ambiguous mtimes during fixup...
status: keep second-ambiguous mtimes during fixup Now that we support the feature, we can keep "second ambiguous" mtime during the fixup phase. These are the mtime that would be ambiguous if we did not had sub-second précions. See the v2 format documentation for details. Differential Revision: https://phab.mercurial-scm.org/D11847
