[wdiff-bugs] colliding documented -t options for mdiff

[Benno Schulenberg]

Hi,

The Info document for mdiff mentions the -t option twice:

`--threshold=NUMBER'
`-t NUMBER'

`--terminal'
`-t'

Which one is right?

Also, it would be nice to have the options ordered in one way or 
another, probably alphabetically by their short forms, maybe 
keeping --help and --version at the start, but then -1, -2, -3,
-A, -i, -l, -n, -p, -t, -w, -x, -y, -z.

Hmm, 'mdiff --help' mentions different single letter options than 
the Info document, and several more of them.
