removing empty parens after function names

[Karl Berry]

rms just requested that we remove the empty parentheses after function
names on, e.g., http://www.gnu.org/software/gnulib/MODULES.html.  He
refers to the "GNU Manuals" node of standards.texi, which ends with:

       Please do not write `()' after a function name just to indicate it
    is a function.  `foo ()' is not a function, it is a function call with
    no arguments.
