Maybe your backslash escaping is wrong. In regular expressions the
grouping is made with \( \) but within Lisp strings backslash has a
special meaning too and those must be escaped "\\( \\)".

Damn! I was passing the double slash to a command I use to help me debug regular expressions.

Hand it the right string and it matches just as expected. (Too much kill-and-yank.)

Maybe now I can track down the real bug.

Thanks for helping me change my perspective.

Is there something I'm missing?
I think we need more information about your code and input data.

Isn't there a difference between "acquittal" and "exoneration"?
