lynx-dev patch - some small changes

[Klaus Weide]

Note: not saved in <http://enteract.com/~kweide/lynx/>;
I don't want to make that a habit, and these dont modify or
correct other changes there.

* Small update for soem chartrans tables, minor comment changes.
* For Unix, use LYSystem instead of system for invoking telnet, rlogin,
  rtn3270 commands.

[ For some non-Unix systems, LYSystem messes around with the passed command
string in various ways, and does some other stuff for DJGPP.  So no change
for those, since I assume it worked before.  For Unix the change prevents
the following occuring with ncurses (at least if USE_SIGACTION is defined):
 - access some (valid) telnet://some.host URL.
 - within telnet client, escape to command level (usually '^]')
 - suspend (usually 'z' or ^Z)
 - resume (fg).  Lynx process gets woken up, redraws lynx screen,
   screen & tty state get messed up. ]
