Subject: [PATCH] fix issue #16

add a blank line in the comments of the headers of the big.po file. This
breaks parsing the headers. msgcat of gettext tools just ignores empty
lines until a header is found and treats everything above as header
comment.

The change to the library itself fixes the tests again, after the blank
linke broke 3.
