dir.c: fix EXC_FLAG_MUSTBEDIR match in sparse checkout

pclouds · gitster · commit ae3cdfe1123d · 2010-11-08T11:39:23.000-08:00
Commit c84de70 (excluded_1(): support exclude files in index -
2009-08-20) tries to work around the fact that there is no
directory/file information in index entries, therefore
EXC_FLAG_MUSTBEDIR match would fail.

Unfortunately the workaround is flawed. This fixes it.
