Melchior FRANZ:

The previous message wasn't totally correct. Strings are now allowed, too. And
the pattern is now '[ -+#]?\d*(\.\d*)?l?[fs]' and *may* be embedded in a string.
There may only be one %s or %f, though. %% is allowed in the preamble/postamble.
(Yes, %ls is allowed, too, and treated as %s.)

Also, "end" is superfluous now.
