A summary of my proposal to add a new E'' string for escape and have
non-E escapes not handle backslashes specially is at:

    http://candle.pha.pa.us/cgi-bin/pgescape

Attached is a patch that emits warnings for \ and \', perhaps for 8.1.
The change to scan.l is the place this is done.  The rest of the patch
is adjustments to prevent our own code from generating warnings.  It
shows a good example of how users would have to change their code.

It passes all regression tests, contrib regression, and initdb runs
without warning.
