Sorry; I was unclear.  I meant: Doesn't jka-compr know how to uncompress
all these files already?

And if not -- why not?

Finding the files is a different issue, and since the file name list
contains "info" in all the names, there isn't much potential for reuse
by etags.

So I would suggest writing some code in jka-compr that would allow
jka-compr to look for compressed files, too (given a regexp), and then
etags could use that, and info.el could be converted (after Emacs 24.1)
to use that, too.
