ECPG and escape strings

Would someone on the interface list look for a fix to this? Thanks.

It turns out I made a mistake in trying to be too smart about adding E''
escapes for ecpg strings that have backslashes. I have reversed the
attached patch to fix the problem. Thanks for the report.

This comes from starting the string constant with ESCAPE_STRING_SYNTAX
in case there is '\' inside the string. Actually I have no idea at the
moment how that made it into. I comment it out for the time being. If
anyone knows a reason for this behaviour please tell me and maybe fresh
up my memory.

CVS commit to come as soon as I'm online again.

I have removed that from CVS. It was a bug I introduced.
