ecpg: Restore detection of unsupported COPY FROM STDIN.

Browse Source 
The ecpg command includes code to warn about unsupported COPY FROM STDIN
statements in input files. However, since commit 3d009e45bd,
this functionality has been broken due to a bug introduced in that commit,
causing ecpg to fail to detect the statement.

This commit resolves the issue, restoring ecpg's ability to detect
COPY FROM STDIN and issue a warning as intended.

Back-patch to all supported versions.
