git wrapper: DWIM mistyped commands
This patch introduces a modified Damerau-Levenshtein algorithm into
Git's code base, and uses it with the following penalties to show some
similar commands when an unknown command was encountered:
swap = 0, insertion = 1, substitution = 2, deletion = 4
A typical output would now look like this:
$ git sm
git: 'sm' is not a git-command. See 'git --help'.
Did you mean one of these?
am
rm
The cut-off is at similarity rating 6, which was empirically determined
to give sensible results.
As a convenience, if there is only one candidate, Git continues under
the assumption that the user mistyped it. Example:
$ git reabse
WARNING: You called a Git program named 'reabse', which does
not exist.
Continuing under the assumption that you meant 'rebase'
