This is a strange and unexpected "feature" in the latest Libreoffice upgrade on Debian stable:
in Writer, I can no longer enter more than one space at a time (between words or sentences)! This is not like at the end of a line where excess spaces are still there just not seen, and the corresponding number of spaces can be deleted - this is different, where additional spaces are simply IGNORED! "How bizzarre!" as they say :) Anyone know how to revert this "fantastic" new feature? :D
