Re: ECPG Connect user :variable problem

All,

It appears that there is an extra space around a " ?" replaceable
string in the preprocessor that should have read "?".  Attached
(and inline) is a patch to /src/interfaces/ecpg/preproc/prepoc.y
that fixes the problem.

Also interestingly none of the test files for the ecpg processor
exercise the "USER :user USING :password" functionality (at least
that I could see - although I'm sortof blind so I might be missing
something :)
