issue332 revisit

[TK Soh]

I'm planning to reopen isue332, by the following observation:

    % mkdir sub1
    % touch sub1/file1
    % hg add sub1/
    adding sub1/file1
    % hg rev sub1
    sub1: No such file in rev e4c586763258
    forgetting sub1/file1

Please let me know if I should open a new issue instead.
