Comment Line manager (Score 1) 344
My line manager in a previous job, hated when I used double spaces in my correspondence! I was taught to use double spaces by my mum, who used to be a professional typist, but I eventually broke the habit, and I only use one space after a full stop now.
I think an option for one or two spaces (as metadata in the document) may have been nicer; that way, it could just tell you if there are inconsistencies. It's stylistic, and not really a mistake. One space is a sensible default, but telling the user that two spaces is a mistake, is a little strange. In any case, at least there is an option to ignore it.
I do think it's a shame that writing style is being homogenised. If you read old books, assuming they haven't been edited out by the publisher, the author will sometimes have some strange use of punctuation, that isn't necessarily wrong, but would probably be flagged by modern word processors as being 'mistakes'.
