# Check whether there are naming conflicts when names are truncated to
# the DOSish case-ignoring 8.3 format, plus other portability no-nos.
# The "8.3 rule" is loose: "if reducing the directory entry names
# within one directory to lowercase and 8.3-truncated causes
# conflicts, that's a bad thing". So the rule is NOT the strict
# "no filename shall be longer than eight and a suffix if present
# not longer than three".
# TODO: this doesn't actually check for *directory entries*, what this
# does is to check for *MANIFEST entries*, which are only files, not
# directories. In other words, a 8.3 conflict between a directory
# "abcdefghx" and a file "abcdefghy" wouldn't be noticed-- or even for
# a directory "abcdefgh" and a file "abcdefghy".
