[elbe-devel] [PATCH] elbepack: log: strip additional ansi escapes used by screen

[Thomas Weißschuh]

Screen emits these escape sequences.
This breaks the build when elbe itself is called during finetuning.

This code is brittle already as only a limited set of escape characters
are filtered.
This will need a better detection, but it seems there is no proper
libraru available to do so.
