Thanks for the cross-platform \r\n CR+LF hint.  Last night I tried to
match \n, but it didn't seem to be working.  Actually it was matching
fine, but my output only had \n in it, and a Windows shell needs CR+LF
to go down a line.

Injecting semicolons is really dangerous though.  What if your file
already has semicolons?  In my code, FILE(...) followed by
STRING(REGEX ...) is destroying the semicolons in the file.  I need to
get to the bottom of that.
