Re: general string replace problem

Marvelous.  Thanks Jeni!

Your first fix solves the problem; the second solution works also.  I'm sure
you're right the latter is more efficient, but my transformations so far are
so short and simple that they take less than a second to execute.  But I'll
happily use your more efficient template anyway.

Note to DaveP: you may want to update the FAQ to point to this corrected
version of Jeni's general string replace template.
