Anyway, I believe that a small patch is needed to better integrate
mm2.7 into slackware.  The first patch tells shownonascii() where to
find the hebrew fonts (they appear to be a standard part of xfree-3.3)
and the second patch is aesthetic (I didn't like more() putting up the
temporary file name in a three-line banner before the actual text).
