This is because: (boundp 'global-text-scale-adjust-resizes-frames) => nil By contrast, if you try C-h f text-scale-adjust RET then the variable text-scale-mode-step in the *Help* buffer does get the link appearance, and boundp returns non-nil for that variable. The reason seems to be that in the latter case typing the "C-h f" command causes face-remap.el to be loaded, whereas in the former case face-remap.el is not loaded. I traced that to a problem which can be demonstrated by the following recipe: emacs -Q M-x load-library RET help-fns RET Now evaluate: (radix-tree-prefixes (help-definition-prefixes) "global-text-scale-adjust") This returns nil, whereas if you do the same with "text-scale-adjust", you get: (("text-scale-" "face-remap") ("tex" "flyspell")) Interestingly, just appending a dash to global-text-scale-adjust, i.e. (radix-tree-prefixes (help-definition-prefixes) "global-text-scale-adjust-") does yield non-nil result: (("global-text-scale-adjust-" "face-remap")) The non-nil result causes help-fns.el:help--symbol-completion-table to load the file: (when help-enable-completion-autoload (let ((prefixes (radix-tree-prefixes (help-definition-prefixes) string))) (help--load-prefixes prefixes))) The load happens inside help--load-prefixes. As result face-remap.el is loaded for text-scale-adjust, and the variables defined in face-remap.el become defined. With global-text-scale-adjust the loading doesn't happen, and the variable stays unbound. This sounds like some snafu with some heuristic somewhere, perhaps in radix-tree-prefixes, or in the code which registers the prefixes to begin with? Can this be fixed, please, so that variables referenced in doc strings would reliably be displayed as links?
