I hadn't noticed...  ISTR it was an issue back when jphoward wrote his
BSD-licensed grep.

However, it's not the same engine - it's Spencer's old engine with
multibyte support added.  IIRC, it performs very poorly compared to the
GNU regexp engine; it would be interesting to see how well the Tcl
engine performs in comparison.
