Wrap or not - was C & undefined behaviour - was Re: tumble under BSD

No; it just assumes that - if the text is not marked as reflowable - that it shouldn't mangle it by inserting line breaks that weren't there in the original. It is obnoxious to have a long line (say, a compile line quoted from make output) mangled into illegibility by gratuitiously inserted line breaks; it is perhaps even worse to have multiple short lines pasted together by gratuitously deleted line breaks. Each of those behaviours is broken. (When applied to text not marked reflowable, that is. If the text is marked reflowable, then either behaviour is fine - but such text needs to not only be marked but be wrapped in accordance with the format=flowed spec.) I can, of course, rewrap text no matter how it's marked, just as I can undo rot13, translate from EBCDIC, etc - but, as with those, it's an additional step and thus impairs readability. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
