If it comes to readability I prefer my last sprintf solution with the twist of changing if to and .

perl -lpe " /(match1|match2)/ and $_ = sprintf qq{%-68s  #$1}, $_ "

Normally I don't like short-circuit expressions, but in this case it really helps clarifying what's happening.

Demo: (win quoting)

>perl -E"say '.' x rand(80) for 1..10" |perl -lpe " /(.)/ and $_ = spr
+intf qq{%-68s  #$1},$_ "

+#.
