  Are they so unreliable ? As for connecting to X server - I think
that this is unnecessary complexity. I think that every terminal emulator
for X sets $WINDOWID, and that this environment variable won't be set under any
other circumstance. Of course the user should be able to turn this feature
off or on (since user can telnet to other machine from xterm and will be
willing to see page titles in xterm titles). So this needs lynx.cfg setting
like  PAGE_TITLE_IN_XTERM_TITLE:TRUE/FALSE/AUTO (true and false are
unconditional settings, and auto will check $WINDOWID value)  and commandline 
option like -use-xterm-title[+-].
