There are long lists of comma-separated values with any spaces on them, rendering the code very difficult to read. I wanted to have something like glasses-mode, but unless I am mistaken, it is not very configurable, so I cannot add new cases as commas separated by spaces, which is mine. Then I thought of overlays, but the manual says that if there are a big number of substitutions, maybe it could be a better idea to use text properties instead. So, from the top of your head, what would be the less painful method to change every comma to a comma+space, or at least change the color of the commas to anything more distinguishable and attach it to the language mode hook? Thanks! -- Alberto
