On reflection, Jonathan, I agree completely. Maybe '%i' and '%e' for
"initial" and "end" - but since few of the codes have any discernible
mnemonic value, that is probably a secondary consideration!
Incidentally, this has the additional benefit of reducing "^" to one
unambiguous meaning and eliminating "$" as a special character.
But whether to actually deprecate them is a choice.
