Ah, I forgot about the texinfo docs. Sorry. I'll try to remember them
next time.

Yes, you're right, it starts from 1. That's what comes of adding the
documentation later, as an after-thought...(bad programming practice!)
And now I look at it again, there's a bug in the regexp (my fault): the
regexp "%\\([1-9]\\)+" currently matches any sequence of 1-9's, which is
clearly wrong. The two possible fixes are:
- Drop the final + from the regexp so that it reads "%\\([1-9]\\)", to
match any single non-zero digit, as per the current docs. (The regexp
group must be kept, because it's used later in the code.)
- Change the regexp to "%\\([1-9][0-9]*\\)", to match any positive
integer, and update the docs accordingly.
It seems unlikely anyone would ever want to refer back to more than
9 prompts in a capture template. (I think back-references in Emacs
regexps are similarly limited to single digits).
On the other hand, whenever someone says "it seems unlikely anyone would
ever want to..." about Emacs, up pops someone who wants to do exactly
that ;-)
Your call. If you tell me which fix you prefer, I can supply a patch if
you want one (though the change is so small I imagine it'll be easier to
do it manually).
