This won't work because `.' does not match a newline. Using `[^$]'
instead should do it.

Ok, but at least it works for oneliners.

Right, that's better.

Just a note about re-builder and regex-tool:
To build a regex to use in a program or with query-replace-regexp, you
can use one of these tools, however, re-builder will build a regex to
use in a program and this regex will not work in query-replace-regexp.
Regex-tool will build a regex more usable with query-replace-regexp.
[0-9]\\{2\\} ==> work in a program but not in query-replace
[0-9]\{2\} ==> work in query-replace but not in a program

$$ What about this $1,000,000 example? $$
Such strings may not be possible in the original data set,
of course, so it might not be an issue.

Then you could use something like
C-M-%% \$\$ \,(if (zerop (mod \# 2)) "\\[" "\\]")

This is great!
Is this an undocumented feature of replace-string? I can't find it in
the help string or the info manual.

David Kastrup once mention this (or a similar example with
`replace-regexp') on some newsgroup or mailing list. I don't remember
if it is possible to use this with M-x replace-... or
query-replace... as well.

I can't find it in the docs neither. Please suggest to document it
(via M-x report-emacs-bug RET).
Bye, Reiner.

M-:(replace-regexp "\\$\\$" '("\\\[" "\\\]"))
It is in fact a feature of the perform-replace function.
Quoting the elisp manual section dealing with this function:
