This makes cursor motion in the indent function consistent with emacs
conventions.  Patch from Mike Wittman.  See issue #8625.

This introduces the unset() command to make it easy to unset CMake
variables, environment variables, and CMake cache variables.  Previously
it was not even possible to unset ENV or CACHE variables (as in
completely remove them).  Changes based on patch from Philip Lowman.
See issue #7507.

ENH:                                                                                                                                                                     ~/CMake/src/Docs

ENH: Using suggestion from Stuart Herring to avoid needing a list of command names in the highlighting table.

ENH: More system variables, more operators, more commands, fix some string issues and some cmake arguments issues

ENH: Added INSTALL command as a placeholder for a future generic install specification interface.  Currently it supports only a SCRIPT option specifying a script to run during the install stage.
