But it seems to be documented behaviour: Note that specifying a value, even nil, marks the variable as special permanently. Whereas if value is omitted then the variable is only marked special locally (i.e. within the current lexical scope, or file if at the top-level). This can be useful for suppressing byte compilation warnings, see Compiler Errors. (https://www.gnu.org/software/emacs/manual/html_node/elisp/Defining-Var= iables.html) Please disregard this bug report. :-) Lu=C3=ADs
