Shawn O. Pearce ad3193a0e5 Fix repo --trace to show ref and config loads
The value of the varible TRACE was copied during the import, which
happens before the --trace option can be processed.  So instead we
now use a function to determine if the value is set, as the function
can be safely copied early during import.
