submenu in Unix PuTTY, and Duplicate Session also in pterm. You do
_not_ want to know how this is done. Be warned.

* - Go through all the config options and ensure they can all be
* configured and reconfigured properly.
*
* - Remainder of the context menu:
*
* - New Session, Duplicate Session and the Saved Sessions
* submenu.
* + at least New and Duplicate probably _should_ be in
* pterm.
* + Duplicate Session will be fun, since we must work out
* how to pass the config data through.
* + In fact this should be easier on Unix, since fork() is
* available so we need not even exec (this also saves us
* the trouble of scrabbling around trying to find our own
* binary). Possible scenario: respond to Duplicate
* Session by forking. Parent continues as before; child
* unceremoniously frees all extant resources (backend,
* terminal, ldisc, frontend etc) and then _longjmps_ (I
* kid you not) back to a point in pt_main() which causes
* it to go back round to the point of opening a new
* terminal window and a new backend.
* + A tricky bit here is how to free everything without
* also _destroying_ things - calling GTK to free up
* existing widgets is liable to send destroy messages to
* the X server, which won't go down too well with the
* parent process. exec() is a much cleaner solution to
* this bit, but requires us to invent some ghastly IPC as
* we did in Windows PuTTY.
* + Arrgh! Also, this won't work in pterm since we'll
* already have dropped privileges by this point, so we
* can't get another pty. Sigh. Looks like exec has to be
* the way forward then :-/
* + icon title appears to be a non-option on Unix.
* + Why the hell did I faff about disabling two of the vtmode
* options? The rest aren't used either in pterm! Work out
* whether they should be, and how they can be.
* + Refresh in the codepage combo is badly broken.
* + `Don't translate line drawing chars' ?? What is this crap?
* It does nothing at all, and where's the option to paste as
* lqqqk? What was I smoking?
*
* - Better control of the individual config box features.
* + SSH packet logging shouldn't be mentioned in pterm, and in
* fact not PuTTYtel either.
* + Keepalives, and the Connection panel in general, shouldn't
* crop up in pterm. (And perhaps also not mid-session in
* rlogin and raw?)
