[cvs-nhc98] patch applied (hat): When navigating with arrow keys in hat-trail, treat a sugared character

Fri May 17 03:30:33 PDT 2002 malcolm * When navigating with arrow keys in hat-trail, treat a sugared character string as a single unit, rather than moving the selection inside the string. Also, ensure that a sugared list (e.g. [a,b]) always has a terminating square bracket, even when the list is cut off at the standard depth. M ./src/hattools/SExp.hs -52 +41
