[pmwiki-users] Long-s Redux

[Peter Kay]

Have you considered the option of using a Replace On Save option to
write the long s to file and then not dealing with markup?  Or do you
specifically want only the display to be affected?

I recall that while I was looking at your earlier work, I was thinking
that your regular expression might benefit from a lookback assertion &
word boundaries.  But if your current regular expression works well,
there's no real reason to change it.
