Hello!
In `emacs-lisp-mode', the counting of the nesting level of forms seems
to be broken in some subtle way. Consider e.g.
(form
(
) WEIRD HIGHLIGHT
x) ;; Unexepected Indentation
It looks like "WEIRD HIGHLIGHT" is wrongly highlighted as junk after a
surplus closing parenthesis, and the subsequent form is also weirdly
indented.
So this particular example is artificial, it occurred for me when I was
writing testing-code with in some personal emacs-lisp project:
;; Example from actual code (abbreviated)
(ert-deftest expr--parser-rule-def-firsts ()
(myert-test-results #'expr--parser-rule-def-firsts
`("The `firsts' function doesn't yet enforce, that every rule
must have a resolvable first."
(((&def RuleA RuleB)
(&def RuleB RuleA))) => WEIRD-HIGHLIGHT-HERE
:WEIRD-INDENTATION-HERE)))
I confirmed the issue in Emacs 25.1.1 64bit (from Chocolatey), running
that same Emacs with "runemacs -q", and with Emacs 26.0.50.1
(self-compiled).
For reference I have attached an elisp file with examples and a
screenshot of how it looks on my system.
regards, Klaus
