Bad alignment in the output of "Print Universes Subgraph"

[YaZko]

A minor QoL nitpick, but in the following code:

Universe u v.
Print Universes Subgraph (u v).

Vscoq displays:

Set < u
< v

while proof general displays the easier to parse aligned version:

Set < u
    < v

Note: it actually displays it correctly in the "Problem" textbox when hovering on it, but not in the "Messages" part of the "Coq Goal" buffer.

This is still not solved with the new pretty printing library, and is related to #835
