Help: Improve formatting of variable documentation

Improve formatting, primarily by:

* Adding links to relevant commands, properties, generators, and so on.
* Converting code, symbols, paths, and so on to fixed-width fonts.
* Hard wrapping lines to 80 characters or less.

 Specify a CMake file that overrides platform information.
 
 CMake loads the specified file while enabling support for each
-language from either the project() or enable_language() commands.  It
-is loaded after CMake's builtin compiler and platform information
+language from either the :command:`project` or :command:`enable_language`
+commands.  It is loaded after CMake's builtin compiler and platform information
 modules have been loaded but before the information is used.  The file
 may set platform information variables to override CMake's defaults.
 
 This feature is intended for use only in overriding information
 variables that must be set before CMake builds its first test project
 to check that the compiler for a language works.  It should not be
-used to load a file in cases that a normal include() will work.  Use
