(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

This has changed a bit since reported a decade ago.  The command now says:

user-error: No next group

Which is the correct thing here -- the command is (now) documented to
"Move forward across one balanced group of parentheses.", and in the
case here, there's no group of parentheses to move forward over.

So this works as intended (`up-list' is the command to use in this
instance, most likely), and I'm closing this bug report.
