[gnu.emacs.sources aka gnu-emacs-@gnu.org is intended for working source
code, not discussion.  Please post questions to gnu.emacs.help aka
help-gnu-emacs@gnu.org]

The regexp looks right to me except for the backslash, because the only
characters within a square-bracketed character set are: [-^

So the regexp is {[^}]+}

Note that even extended regular expressions are mathematically incapable
of matching nested/recursive patterns.
