From dfc064613e8f954bf2b3999ef99a0fb1b410b0fb Mon Sep 17 00:00:00 2001 From: Lars Schneider Date: Thu, 1 Jun 2017 09:56:59 +0200 Subject: [PATCH] convert: move multiple file filter error handling to separate function Refactoring the filter error handling is useful for the subsequent patch 'convert: add "status=delayed" to filter process protocol'. In addition, replace the parentheses around the empty "if" block with a single semicolon to adhere to the Git style guide.
