Log Message:
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.
