Because it contains the string file:// in it. I can confirm that this bug is still in Emacs. The problem is this regexp: (defvar makefile-dependency-regex ;; Allow for two nested levels $(v1:$(v2:$(v3:a=3Db)=3Dc)=3Dd) "^\\(\\(?:\\$\\(?:[({]\\(?:\\$\\(?:[({]\\(?:\\$\\(?:[^({]\\|.[^\n$#})]+?[= })]\\)\\|[^\n$#)}]\\)+?[})]\\|[^({]\\)\\|[^\n$#)}]\\)+?[})]\\|[^({]\\)\\|[^= \n$#:=3D]\\)+?\\)\\(:\\)\\(?:[ \t]*$\\|[^=3D\n]\\(?:[^#\n]*?;[ \t]*\\(.+\\)= \\)?\\)" "Regex used to find dependency lines in a makefile.") Of which I can only say... "eek". I wonder -- has anybody considered rewriting make-mode.el using syntax-ppss? Or is the syntax just too intractable for that? --=20 (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
