toggles in nano.h, toggle_init(), toggle_init_one() in global.c

called from shortcut_init(), and do_toggle in nano.c. Also

moved the signal code into a separate function in nano.c called

signal_init().

signal_init(). Moved "struct sigaction act"into a static in
|

nano.c.
|

- Changed from Alt-key symbol (@) which is completely nonstandard
|

to the *nix "Meta" symbol (M-). Changed help_init to show

the M-key usage and the help text to explain keys whcih generate

do_toggle()

- Added checks for no help and no wrap mode, and print opposite

do_suspend(), do_cont():

- New functions, handle suspend signal in a Pico-like manner and

work with Meta-Z.

- winio.c:

total_refresh()
|
||||
- Added edit_refresh() call to actually update the screen if messy.
