csh with spelling correction

[James David Hobbs]

tcsh does a very restricted form of spelling correction.  
Here is a sample interaction with tcsh:
% cm -o out main..c <cr>
cm: Command not found.
% cm -o out main..c
   ^ use editing commands to get last line, and move cursor here.  
     Now hit <esc-s>
% c -o out main..c
   ^ it got a command but clearly not the desired one
% cc -o out main..c
   ^ if add c here and hit <cr>
No source file main..c
% cc -o out main..c
		   ^ if get last command and hit <esc-s>
% cc -o out main.c
		   ^ now hit <cr>
%

Here is how a past shell of mine worked:
% cm -o out main..c
cm: Command not found.
The command has been corrected
? cc -o out main.c
y <cr>
%

The type of spelling correction that I am talking about is 
syntax-sensitive.
