Stevie was posted in comp.sources.unix on june.   (It is a good subset of vi,
only tricky visual commands and many 'ex' commands are missed)

Meantime i have splitted search.c many times and found the problem.
It was a 'internal static declaration of a procedure'
Above this fix is listed and other bugfixes   
Stevie uses system V ioctl, which is also modified for minix (Ver. 7)
Some changes are included by ifdef so you must define MINIX.

If you see the changing in search.c at line 92, you could think i have
improved efficiency. That's not the reason for it. If i call strsave
unconditionally, then -!- the string received by strsave is NOT the
same as the string given in the call of strsave !! The first two chars are
changed. So the 'n' command wasn't working. I think, this is a bug in
the minix compiler.

Remaining problems are:
   scrolling (because minix tty don't support all ansi escapes)
	slow - for ^E the full screen is updated
	probably stevie can improved to clever use the existing features
	( ESC M  for ^U )
   search with '^' (don't know why)
   cursor keys don't work - they generate three chars beginning with ESC
	- stevie expect one char  (keymap.h)
   the u  (undo) works only after a r command - Tony Andrews is asked to
	improve that.
   dW works as dw
   editing an empty file hangs stevie (don't know why)
   the possible file size is limited
	(about 24700 Bytes, a little more than mined).
   editing an empty file hangs stevie

If Stevie writes the file back, it renames the existing to .bak and creates
it new. After successfully writing the .bak is deleted.
Fatal consequence: A write protected file will overwritten if you have
w-permission on directory.
Because of this i have suppressed the renaming if there is no write
acess for the file. Also the [Read only] message is displayed.
Permissions are restored on the new file and (if possible,) the owner.

For the :e  command i have added handling of %, but only one % is expanded.

Stevie can work with a tag file!! But knows anyone a PD ctags program?
For linking you must increase the stack of asld (45000).
My system for the test was 1.3a.
