Are you sure you need to put all those newlines into the output?
# man iwlist|col -b|perl -anwe '/iwlist \[interface\]/||next; print
"---$F[-1]---------\n"; system("iwlist",$F[-1])' 2>&1|wc
186 490 4123
# man iwlist|col -b|perl -anwe '/iwlist \[interface\]/||next; print
"---$F[-1]---------\n"; system("iwlist",$F[-1])' 2>&1|sed /^$/d|wc
134 490 4071
On can save many lines and the output looks much nicer without them.
Also is using stderr instead of stdin really called for?
