[small bug] Surprising "Did you mean this?"

[Matthieu Moy]

Hi,

The following is quite surprising:

  $ git tags 
  git: 'tags' is not a git-command. See 'git --help'.
  
  Did you mean this?
          status
  
I would have expected git to propose me "tag" (1 character removal),
while "status" is quite far from "tags" (remove g, add u, add another
t, shuffle and you're there).

my 2 cents,

That's the Deveraux(?) addendum in action. shuffle+replace = 3 in the
distance score, while remove = 4 (I think).

Typos by users accustomed to computers are more often of the shuffle
(haed vs head) or replace (hwad vs head) kind, while those less
accustomed often fumble more and press more keys. For this case though,
I agree it gives a rather strange result.

It looks like the addition of a character at the end (more exactly
the deletion of a character in the possible substitution) is bogus.
I am testing a patch.
