Trivially so by generating an or-pattern: "singular text\\|plural text". 
Anything better is a matter of optimisation, basically a diff algorithm (or 
just prefix and suffix merging).

Is it practical, though? For %s, we would need to generate a match-anything 
subexpression, even though the argument is much more constrained in practice.
