Does tail still need the 4K byte limit?

Also, fmt. I use fmt to fix up files transferred from various
pc word processors, which often delimit *paragraphs* with nl, or cr-nl.
fmt has a hardwired BUFSIZ (1024) character limit per line. That's not
enough for many purposes. Arbitrary (short) limits should go. Yes, I can
fix my copy of fmt, but in general, limits should be generous, especially
those that pertain to a program's core functionality.
