Subject: Pipe/Stdin rule to append/prefix

As an experiment, I'm curious... perhaps this is a feature request at the
same time.
I've tried using -pipe to append -i=digits to the second instance of john
words from a wordlist. I'd like pipe to support appending/prefixing stdin,
but I suppose first that pipe and wordlist would not be mutually
exclusive/duplicate's...

john -i=5digits -stdout | john -pipe -w=wordlist.txt  -rules=prefix
hashes.txt

121988password
12100password
220123password
2password
121100password
121101password
121987password
222password
22285password
etc..

Perhaps it's not even the best use of john, if it can be done in a oneliner
or a few lines of something else I'm all for it.
I'd love to have rules that can use incremental as prefixing/suffixing
(within reasonable limits)

[List.Rules:prefix]
A0 {inc=digits,5}
A0 {inc=alnum,4} excuse the bad pseudo code examples, but assume that
digits and alnum refer to the standard digits/alnum.chr files.

Those are some of my ideas, again they might be better implemented
elsewhere, and then piped into JtR I'm not sure.
