That should be the fix, since it's a space problem.

The problem with doing this is, the lines need to be displayed
immediately after the refname,
followed by a newline, what you're suggesting breaks that flow.
We could pass a boolean to show_ref_array_item() and print a newline if no
lines are to be printed and probably print the newline in tag.c
itself, but seems confusing to me.

I find this more readable, since the space is clearly visible, unlike
format = "%(align:15,left)%(refname:short)%(end) "; in which the space
after %(end) is easily unnoticeable.
