I will if I can make it happen again.

The only thing I can think of at the moment is that this morning I may
have used cut-and-paste to write the input file or to read in the
commands, either of which would have lost the tabs.

The original reporter's mail had no tabs at all, but it was not an
attachment and it had had lost all its tabs along the way.  His input
script came from 7.0 pg_dump.  I am following up with him whether there
are actually tabs before the empty fields in that pg_dump output.
