Summary:                    Regular expression documentation doesn't match
command effects.
Description: 
The documentation for string(REGEX ...) says:

   ()        Saves a matched subexpression, which can be referenced 
             in the REGEX REPLACE operation. Additionally it is saved
             by all regular expression-related commands, including 
             e.g. if( MATCHES ), in the variables CMAKE_MATCH_(0..9).

This doesn't match the behavior of file(STRINGS ... REGEX ...)!


Steps to Reproduce: 

$ echo foo > /tmp/foo
$ cat CMakeLists.txt
file(STRINGS "/tmp/foo" tmpvar REGEX "^(foo)")
message(STATUS "*** ${CMAKE_MATCH_1} = foo")
$ cmake .

results in:
-- ***  = foo

not
-- *** foo = foo
as expected.
