Summary:

A function call with no parameters should not have any spaces between the parenthesis.
The current fixer seems to remove some spaces, but still leaves one.

Most likely cause: PEAR.Functions.FunctionCallSignature

Example:

File: ./src/wp-settings.php

Source:

ms_cookie_constants(  ); // Line 282
wp_templating_constants(  ); // Line 393

Fixed as:

ms_cookie_constants( );
wp_templating_constants( );

Expected fix:

ms_cookie_constants();
wp_templating_constants();
