zshrc: Fixed `minimal-shell' function
Well, it was actually completely broken. Because I fed an absolute path
name into `check_com()' without testing it - instead of using the
obvious test.
This also fixes an annoyance:
If infocmp returns an octal code such as this:
backspace='\177'
That screwed up our special-string resolution, because mksh's `print'
builtin doesn't like \177 style octals. It *requires* them to look like
this: \0177 (leading zero).
We now just translate these strings like this:
\\[1-7][0-7]* => \\0[1-7][0-7]*
That should be fairly safe. - And this time, mika and me actually tested
the code before committing it. :-)
