SourceForge is only making things worse, currently, because the page load times are only still increasing. If you want to get quicker results, please go to the SourceForge Community forum by clicking on the Feedback link in the lower right corner of this page. Ask to "give us the old SourceForge back".
I would look at some of the functions in the TextFX Vix plugin.
Sorry, not TextFX Vix, TextFX Viz!
Or do a regex search and replace: .*delete this line.* with nothing (the '.*' matches all the excess).
This will then leave blank lines where the lines with "delete this line" were.
