FMSLogo Code

This commit was manufactured by cvs2svn to create tag 'VER-6-10-1'.

Add a note that you can get the origin of an array with FIRST. This non-obvious fact resulted in a support request on the Logo forum, so I decided to document it where the user would look for the information.

Bump the version to 6.10.1 for a bugfix release.

Replace the word "constituent" with "item", in accordance with STYLEGUIDE.TXT.

Improve the formatting a little bit and fix some minor typos.

Fix bug #1545911: The questionmark inputs in template-based iteration are now correctly restored when the template goes out of scope.

This bug is a regression introduced in FMSLogo 6.10.0 that came with fixing some crashing bugs in APPLY. Because this bug causes a breaking change in the exiting Logo programs, I am going to release a bug-fix build out of the normal release cycle.

Test that the question mark list gets restored after APPLY returns.

Update expected test log. This includes:
* New tests for REDUCE, PENSIZE, SETPENSIZE.
* Some bugfixes.

Add regression tests for REDUCE.

Add a regression test for bug #1545911, which is that nested questionmark template are not restored when an inner template goes out of scope.
