[Matthias Clasen <matthiasc src gnome org>]

commit 94bcdd32174bd10d97ba7b909b6a8a250bbab9f7

    Strip leading and trailing whitespace from filechooser save filenames
    
    This makes a local copy of the file part of the entry to strip it transparently
    Since this is assumed to be a mistake, the user is not notified.
