cmake-mode.el: dedent a hanging parens
Suppose you have this function call:
FancyFunction(
NAME just
OPTION testing
) # this parens should be at previous indent level
With this patch, the indentation will be
FancyFunction(
NAME just
OPTION testing
) # now it's correct
Multiple closing parens won't decrease indentation more, but the current cmake syntax doesn't allow nesting function calls anyway.
