Hmm, what do we want {^ing Mc^} or {^a^} to do? Should suffix rules be applied? If not, else is right. If so, we should remove the line entirely.

Thanks for the comment!

P.S.
For my own edification, I put together a pseudo-EBNF description of Plover rules:

	rule := (rule_char+ | command)*
	rule_char := [^{\]
	rule_char := '\' .
	command := '{' command_contents '}'
	command_contents := '^' [^}^]* '^'
	command_contents := '^' [^}^]*
	command_contents := [^}^]+ '^'
	command_contents := '-|'
	command_contents := 'PLOVER:' [^}]*
