[PATCH 0 of 2] backout of changeset b4903debbe3b

[Giorgos Keramidas]

Changeset b4903debbe3b in mercurial/crew breaks "hg commit"
for directory entries.  This means that even if "hg stat" shows
something like:

    % hg stat .
    src/bin/ls/ls.c
    src/bin/ls/ls.1
    src/bin/ed/ed.1
    %

It's no longer possible to commit a part of the changes with:

    % hg ci src/bin/ed
