Before this patch, misplacing a special must-be-first option for dispatching to a subprogram (e.g., postgres -D . --single) would fail with an error like FATAL: --single requires a value This patch adjusts this error to more accurately complain that the special option wasn't listed first. The aforementioned error message now looks like FATAL: --single must be first argument The dispatch option parsing code has been refactored for use wherever ParseLongOption() is called. Beyond the obvious advantage of avoiding code duplication, this should prevent similar problems when new dispatch options are added. Note that we assume that none of the dispatch option names match another valid command-line argument, such as the name of a configuration parameter. Ideally, we'd remove this must-be-first requirement for these options, but after some investigation, we decided that wasn't worth the added complexity and behavior changes.
