They do.  From the re_syntax (3tcl) man page:

         \m    matches only at the beginning of a word

         \M    matches only at the end of a word

         \y    matches only at the beginning or end of a word

         \Y    matches only at a point that is not the beginning or end  of  a
               word

Paul.
