[STR Active]

Version: 1.3-current
Attaching a patch to simplify fl_measure()'s handling of symbols.
Result should give same results as old code, but should probably
check odd combos of @ symbols.
Suggest making unittest specifically check @ symbol measurements
for all odd conditions, including @@, abutting @@'s, etc.
Will leave patch here for a while to sleep on it and for comments,
and commit on a later date.
