induction/destruct : nicer syntax for generating equations (solves #2741)
The ugly syntax "destruct x as [ ]_eqn:H" is replaced by:
destruct x eqn:H
destruct x as [ ] eqn:H
Some with induction. Of course, the pattern behind "as" is arbitrary.
For an anonymous version, H could be replaced by ?. The old syntax
with "_eqn" still works for the moment, by triggers a warning.
For making this new syntax work, we had to change the seldom-used
"induction x y z using foo" into "induction x, y, z using foo".
Now, only one "using" can be used per command instead of one per
comma-separated group earlier, but I doubt this will bother anyone.
