Dear AucTeX maintainers, The commits
d0a57d8d Fix math macro folding to not consume subsequent brackets
33f9eb07 Fix TeX macro end detection in some edge cases
break the folding of math macros with a function spec.
E.g. evaluate
(setq TeX-fold-math-spec-list `((,(lambda (text) (propertize text 'face
'(underline))) ("underline"))))
and open the attached file. Do `M-x TeX-fold-mode RET` followed by `M-x
TeX-fold-buffer RET`. This results in
[Error: no content or function found]
getting displayed instead of \underline.
My config has many folding specs which are functions and all of them
exhibit the same behavior.
Reverting the commits above fixes the issue.
Thanks,
Rahguzar
