'inctxdirs()' should examine 'f in dirstate.rdirs()' for removed file
(fixed in patch #18).

In addition to it, exisiting 'f in dirstate.dirs()' should also
examine it for removed files.

So, I defined 'inctxdirs()' as function to centralize such
modification to it.

In working context, 'inctx()' should examine 'f in dirstate' instead
of 'f in ctx' for removed files (fixed in patch #12).

I defined 'inctx()' as fucntion, because this switching may lose code
readability.
