Changes 0.11.52:
* Russian translations updated. Thanks M. Zaripov.
* Added test for nested Move of directories. Thanks to John H.,
  "m3", and F. Cosolete for reporting variants of this.
* Hopefully fixed broken logic in Copy that caused it to abort
  too soon when skipping a directory. Reported by M. Bunkus.
* Fixed bug that caused DirParent to always (internally) look like
  it failed, which stopped sequences from continuing past the
  command. Reported by C. DeeDee.
* The SelectSuffix command will now use the first bareword argument
  as the suffix. Suffixes are assumed to start with a period (.),
  so running "SelectSuffix action=toggle bmp" will toggle the sel-
  ection state of all files whose names end in ".bmp". This was
  suggested by C. DeeDee.
* The left arrow key now exits the text viewer (suggested by
  F. Cosoleto).
