Howdy again all. I just discovered another semi broken package in the recent SUMO release: whitespace-mode. [ Apparently I should have been checking out some of these changes while they were still in pre-releases. :) ] It looks like a new whitespace.el has been added to apparently replace the whitespace-mode.el since the former is supposedly a superset of the latter, however it is not. AFAICT the new one (whitespace.el, snagged from FSF apparently) only highlights "bogus" whitespace (i.e. stuff that it wants to clean up, like trailing whitespace) whereas the original whitespace-mode.el will highlight all tabs and/or spaces in the file (I use it for showing tabs in Makefiles, tab deleminted data files, etc). So now whitespace-mode doesn't exist, as the prefix 'old-' has been added to everything in whitespace-mode.el which I'm guessing was done to keep from conflicting with similarly named vars in whitespace.el. So...easy enough for me to work around this by manually loading the whitespace-mode.el and turning it on with 'old-whitespace-mode' (and changing my setting of vars for its behavior by prefixing them w/ 'old-') but I found it a little annoying that this had changed so much. Seems to me that a couple of minor "under the cover" type changes to whitespace-mode.el would probably have sufficed to prevent conflicts between the two packages. If I'm feeling ambitious later (and get a few moments to spare) I may submit a patch to "ressurrect" whitespace-mode. But I figured this email could possibly help save someone else who hits this problem a little time in the meantime. Chuck -- Charles K.
