- rsprintf("<textarea rows=%d cols=%d wrap=hard name=\"Text\">\n", height, width);
+ rsprintf("<textarea rows=%d cols=%d name=\"Text\">\n", height, width);

my vote is to remove "wrap=hard":

1) I try to read the specs and my head explodes: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/textarea
2) textarea should just accept input typed by user, should not try to "neatify" it. if user wants long lines, we should let them.
3) this bug (introduced in recent safari, the best I can tell)

K.O.
