    Hmm, now that's true.

    How's this for another try? (logwidth = 38, adjustable per taste)
    Myself I'd say this is crap and a nice 140-char xterm will do much
    better (you're going to see "long" lines anyway, look at the NTFS
    entry below).

    $ ./fmtcl3.pl /usr/src/ChangeLog-2.5.14
