Revert inadvertant change in pg_config behavior

jconway · jconway · commit fc8a81e3e73e · 2016-02-17T10:00:34.000-08:00
In commit a5c43b8 the behavior of command line pg_config was inadvertantly changed to include the config name when specific configs are requested, similar to when none are requested and all are emitted. This breaks scripts that expect to use pg_config for e.g. PGXS. Revert the behavior to the previous.
