Обсуждение: pgsql: Cosmetic improvements for options-handling code inECPGconnect()

Cosmetic improvements for options-handling code in ECPGconnect().

The comment describing the string format was a lie.  Make it agree with
reality, add/improve some other comments, fix coding style for loops with
empty bodies.  Also add an Assert that we counted parameters correctly,
because the spread-out logic for that looks pretty fragile.

No actual bugs fixed here, so no need to back-patch.
