                                               Fix this problem.

So, does this fix the problem by changing
directory_exists_in_index_icase() to be more liberal in what it
accepts, or callers to be more conservative in what they pass in?

It places the onus upon the caller. As mentioned in the cover letter
[1], I was not happy with this solution. Junio felt likewise. A
follow-up series [2] fixes both directory_exists_in_index() and
directory_exists_in_index_icase() to be more liberal in what they
accept, relieving the caller of the burden. By the time that series
was posted, however, Junio and Peff had decided that a fix at a more
fundamental level would be better (a conclusion with which I agree,
but for which I do not yet have sufficient knowledge about git
internals to implement). In the meantime, as an interim bug fix, Junio
decided [3] to apply the patch to which you responded (but with an
updated commit message).

Please forgive my laziness.  I ask in order to save future readers the
time of digging into the code.
