Info-index-alternatives

[Juri Linkov]

The message displayed by `Info-index-next' is not informative in
regard to the number of remaining alternatives that subsequent `,'
commands will find.  The patch below displays the number as the total
size of `Info-index-alternatives' minus the currently found index
entry.  Since `Info-index-alternatives' is a ring, if for example
the length of `Info-index-alternatives' is 16, then the message
"(`,' tries to find 15 next)" is correct, because it is true that `,'
will find them regardless of the current position in the ring.
