  Mosaic for X sends it, but in a totally broken way.  According to the
spec, there should be at most two tokens on the line.  Something like:

User-Agent: XMosaic/2.4; libwww/version#

  Mosaic sends:

User-Agent: NCSA Mosaic for the X Window System/2.4; libwww/version#

  Not exactly adherent. :) Easy enough to change though.  mo-www.c needs to
change char*HTAppName = "Mosaic-X";

  Emacs-w3, violaWWW, and lynx all send the correct User-Agent field.

  Emacs-w3 and lynx are the only ones I know of that implement this
