Subject: 199.17

The v200-tagged code in CVS for MzScheme and MrEd is now version 199.17.

The changes are relatively minor:

 * Added `read-accept-quasiquote’ to control whether the reader
   accepts backquote and comma in input (for DrScheme’s teaching
   languages).

 * Fixed bugs in the `rename’ form of `require’.

 * Changed menu-item% and checkable-menu-item%’s `menu’ initialization
   argument to `parent’ (to match the docs and the rest of the
   toolbox).

 * Corrected the documentation, changing `help’ initialization
   arguments for menus and menu items to `help-string’.

 * Added an optional argument to text%’s get-visible-line-range and
   get-visible-position-range to control whether the computed range is
   for all displays (the default) or only the current one.

 * Added `label’ initialization argument to canvas% and editor-canvas%
   (since they implement window<%>).

 * Renamed "2k" to "PGC" (for "precise garbage collection").

 * Upgraded to gc 6.0alpha9.

The MzScheme, MzLib, and MrEd doc bundles have been updated.
