pgsql: Clean up psql variable code a little: eliminate unnecessary tests

From
tgl@postgresql.org (Tom Lane)

Log Message:
-----------
Clean up psql variable code a little: eliminate unnecessary tests in
GetVariable() and be consistent about treatment of the list header.
Motivated by noticing strspn() taking an unreasonable percentage of
runtime --- the call removed from GetVariable() was the only one that
could be in a high-usage path ...
