# Use gensub for converting tags: itz Sep 30 1998
#
# However, the gensub function is gawk-specific, and we want things
# to work with original-awk too (for portability).
# Therefore, use a normal gsub, even though it's a subobptimal solution
# as it may step in extra braces. The good solution will be piping to sed,
# or match, extract subesxpression, replace, reinsert -- bleah...
