Subject: [PATCH] report line number for Prototype not terminated
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously COPLINE was updated (to the end of the file) before
reporting the error, which wasn't useful.

Petr Písař: Ported to 5.28.1 from upstream's
7122d783e33c1d4b9b5a037eef231fae4c2d76cd.
