My apologies to Mr. Markupexpr.php -- he robustly handles parenthesis and
doesn't even blink at the nesting. "Piping" seems to work effectively in
this simple test case.
{(tail n=5 (tail prefix="Lines from PAGENAME:" n=3 file1 file2 file3))}
This gives the last line of file2, a prefix line of "Lines from file3:" and
then the last 3 lines of file3 -- all that totals 5 which is the number of
lines the outer (tail...) was looking for.
I put lines at the end of file1, file2, and file3 that had parens and there
was no difficulty at all.
