Fish's highlighting of incorrect commands could be better if it highlighted
the characters where the command differs from the closest recognized
command, This could be from left to right, or some more sophisticated
matching algorithm like smallest string manipulation. Use a simple
algorithm if the typed command name is long.
As for suggesting a correction, Zsh's solution (with a Y/n prompt) works
for me. Yes, it is modal, but it's not obtrusive. Typing anything other
than 'y' has the same effect as the original command would, that is, an
error message that the command name does not exist.
An alternative solution is to put the suggested correction in the command
line so the user can press Enter to accept it, or Ctrl+C or Ctrl+U to
erase. If the user types any characters, they would be added to the end of
the command. This is modeless.
