Comment (by pbruin):
Replying to [comment:4 wuthrich]:
> I see that you changed ell.gp. Is this good ? It is very very likely
that the next update of simon's scripts will forget to make this patch-fix
of a upstream file. Would it not be better to tell the author to change
this in his version and we update our file ? This is a genuine question as
I am not sure what is better. One thing to bear in mind is that it seems
that Denis has not been very active on the bugs in his script recently.
I reported the bug to Denis and sent him the same patch used for this
ticket. Something similar happened with #15483. So far, these are the
only two tickets in which changes to `ell.gp` were made. Hopefully he
will make these fixes (or alternative ones) in the next version. (We
don't know when that will be, but the last version of `ell.gp` dates from
2011, while all his other programs were updated last January.)
