I was experiencing the issue discussed here at StackOverflow http://stackoverflow.com/questions/4920210/what-causes-this-graphical-error-in-emacs-with-linum-mode-on-os-x. The suggestions boil down to a few choices * stop using dynamic format and explicitly set a format like "%7d ". Note the trailing space. * specify a function to return the format which will include the trailing space * edit the source to ensure a space is added when the line number is finally rendered. I dislike all three choices. Choice 1 will usually eat too much room on the left. That is why dynamic was created in the first place. The format handler routine option in Choice 2 is inefficient to implement since the user will need to basically reimplement the dynamic logic and this is called for every line in the file. If you follow some of the links on StackOverflow there are several solutions to this and similar problems that all reproduce the dynamic logic. I finally chose to implement a variation of option 3 which is attached as a patch. Basically it lets the user specify a padding value to added when the line is rendered. The patch is small, easy for a user to implement and efficient in execution. It certainly seems easier than the solutions involving defadvice and the dynamic format logic. For now I have a fork of linum in my .emacs.d/site-lisp. My patch to linum is attached. Feel free to change the name of the customization variable or improve the help text. Sean
