[PATCH] git-ls-files.txt: clarify -x/--exclude option

[Jay Soffian <jaysoffian@gmail.com>]

Since b5227d8, -x/--exclude does not apply to cached files.
This is easy to miss unless you read the discussion in the
EXCLUDE PATTERNS section. Clarify that the option applies
to untracked files and direct the reader to EXCLUDE PATTERNS.

Well, at least we can clarify the man page to reduce likelihood
of future confusion.
