[PATCH 4/4] line-log: convert an assertion to a full BUG() call

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

The assertion in question really indicates a bug, when triggered, so we
might just as well use the sanctioned method to report it.
