Sparse complains thus:

Hi Torsten,

When you re-roll your 'tb/safe-crlf-output-fix' branch, could you please squash this into your patch (corresponding to commit 9c7b132f, "convert.c: more safer crlf handling with text attribute", 01-04-2016).

>From an earlier email, I see that you are aware that t6038 is failing, so

I won't look into that.

Thanks!

ATB, Ramsay Jones
