no-space-function isn't always respected

[fenuks]

I tested this on the latest tagged version (5.4), as well on the latest git version.

This feature is described

# Remove the space character between a function call and the open parenthesis that follow.

, but it doesn't work in all cases.

$ echo 'SELECT app_public.hello ('test'); DROP FUNCTION IF EXISTS app_public.hello (a text);' | pg_format --no-space-function
SELECT
    app_public.hello (test);

DROP FUNCTION IF EXISTS app_public.hello(a text);
