In mathed it is assumed that a labeled line is also implicitly numbered.
However, latex allows to label an equation without numbering it.
The label is then assigned the value of a nearby numbered one.
This commit drops the above mathed assumption in order to allow to import
valid latex code with a labeled but not numbered equation line.
The screen representation omits the line number and encloses the label
in square brackets for further differentiation. However, it is still not
possible to label an equation without numbering it using the GUI.
