Sounds like an Emacs bug to me "\\s " is working (in
fundamental-mode). Anyway newline isn't whitespace in
"most" modes. In quite a lot of languages a newline ends a
comment. To make your regexp reliable i would use something
like "abcd\\(\\s \\|$\\)" (note that this will match "abcd"
at the end of the buffer too w/o a final newline).
BTW: M-: (syntax-after (point)) RET may be useful.
