This is so completely random, and not really code related, but it was huge at the time (circa 1990). I was compiling large bibliographies of research documents for NSF that eventually had to be read into Word Perfect 5.1 for DOS for printing. We had written a very complex system of WP macros to search for tags that we programmatically put in the file, but they took forever to run and would often crash. My colleague and I found that we could only use search/replace to send begin/end pairs of tags for any formatting code (e.g. bold, italics). However, if we replaced the closing tags first, then the opening one, WP would notice that there were pairs of empty tags and get rid of the extra closing tag so that the underlying text would be formatted properly.

We were doing this everyday, so it cut the processing time from many hours to seconds. We swore each other to secrecy about this development and marched off to Dunkin’ Donuts with our giant ice coffee belt-loop holsters to celebrate.
