Quoting David Powers cyborgk@gmail.com:

PS. Why does PD always mangle the text comments I input? My carriage returns always disappear or are misplaced... This makes it IMPOSSIBLE to make nice reading help documentation (making me lean towards a pdf help file for the moment.)

this is because pds "comment" has currently no notion of newlines: when you save the patch, all newlines will be stripped from your comments; lines will be automatically broken at some magical boundary (which you cannot change).

however it is still POSSIBLE (though unpractical) to make nice help-patches with "customized" linebreaks by not using newlines within comments but new comments instead.
