Fixes #575.

@radare @XVilka please take a look and review.
Don't think that this is the correct solution but it fixes the test.
First of all printing in libr/cons/cons.c produces some sequence of chars that breaks the diff.

secondly, the output FUNC > is not expected.

thirdly, filter_refline2 does some ugly shit and this was the main case to the #575 mess.

And lastly there was a dash hardcoded instead of proper LINE_VERT.
