non existing table error message changed?

While running the regression test on current, I noticed some tests
faild due to a change of error message for dropping non existing
tables.

Relation foo Does Not Exist!

--->

Relation foo does not exist

I just want to know the reason for those changes.

Not sure, but the second is better. I have modified the regression
tests.

To make the error messages consistant in style. I hope this is not
causing trouble for apps...
