The DJGPP ports of GNU software can only be held responsible to document
what are the deviations in the functionality from the original programs on
Unix platforms.  Other than that, you get whatever docs there are (or
aren't) in the original GNU distributions.  In this case, GNU Grep comes
with a man page as its only docs (you will find it in the binary
distribution as `info/grep.doc') and GNU Sed comes with no docs at all,
incredible as it is.

AFAIK, it shouldn't.  GNU Sed calls the regular expression library with a 
syntax that doesn't include support of such character classes.
