LYNX-DEV Bugfix for DOS (version ac-0.108)

[Doug Kaufman]

There has been a persistent bug in the DOS version (I don't know if
this also affects the Windows port), wherein exiting via CTL-C or
via CTL-BREAK only works if BREAK is set to "ON" in DOS before lynx
is invoked. The following patch fixes this problem and returns the
BREAK setting to what it was before lynx was invoked (as long as lynx
exits normally). If exiting via CTL-C or CTL-BREAK, BREAK will be left
set to ON in DOS regardless of the original setting. Perhaps someone
more knowledgable in C can alter this to meet any usual programming
conventions. This patch uses PDCurses functions, so it should be
portable to the Windows version that uses PDCurses.

The patch is against ac-0.108. I haven't had a chance to download the
more recent versions.
