Posix says the word boundaries for ^W in insert mode are characters that aren't <blank> or <punct>. So you deal with the character before the cursor (`o'), and delete to a character that isn't <blank> or <punct>. Since the `o' is in neither character class, it's the word boundary, and you don't delete anything. FWIW, ksh93 behaves the same way (but beeps annoyingly). -- ``The lyf so short, the craft so long to lerne.'' - Chaucer ``Ars longa, vita brevis'' - Hippocrates Chet Ramey, UTech, CWRU c...@case.edu http://cnswww.cns.cwru.edu/~chet/
