New description:

 For example, !FileZilla misparses filenames containing CR (U+000D), such
 as "blamp \r$(curl noncombatant.org)" currently in the public directory of
 the test grid. It appears to treat the characters after the \r as a
 separate line (judging from the Message log when 'Edit menu | Settings...
 | Debug | Show raw directory listing' is checked).

 I think we should be stripping out children with names containing
 characters below U+0020 when found in a directory, and rejecting attempts
 to create them. See also #731.
