\b will work whether the next character is a space or a ] ?  (the only
two possibilities I'm concerned about...

And to get it so it could take t1 or r3 could I do

'/(\n?)\[([trc][0-9]{0,1}\\b)(.*?)\]/e'

Thanks again for your help with these bewildering patterns.  Though
they are beginning to make a bit of sense at least...
