OK, thanks for the explanation; I didn't understand
the joke, and I wasn't expecting such a fast patch.
And thanks for the fast patch!
====================
While we are patching model-howto.html, let me point out that
it contains the following line:
position-norm + offset -1 * factor 120 clamped to min/max -90:0
That needs repair in at least three ways:
1) The documentation says (and observation confirms) that the
offset is applied *after* the factor.
2) It's offset-deg here, not offset.
3) The presentation violates time-honored algebraic conventions.
It would be better typset as a table with two rows:
position-norm * 120 + -1 clamped to [-90, 0]
<property> * <factor> + <offset-deg> clamped to [<min>, <max>]
===============
Tangential question:
As Emerson put it, a foolish consistency is the hobgoblin of little
minds, adored by little statesmen and philosophers and divines.
But given that it was considered necessary to have <offset-deg>
rather than <offset>, why do we have <min> rather than <min-deg>?
Just curious.
==================================================
On the more general subject of patching things: I was pleased by
the high-speed response to the <offset-deg> issue. I was also
surprised ... because there has been no discernible response to
some other bugs I have reported, including ones where I went to
a lot of trouble to find the bug and provide a patch.
In particular, I would have thought that the fix to hsi.xml
would have been completely noncontroversial, and I was sorta
hoping it would have made it into cvs by now. Or, if there
is something wrong with this patch, would somebody please
explain and/or provide something better?

Similarly, the handling of non-unique navaid identifiers was
on the TODO list. Now it's done ... or at least it's done
chez moi. If other folks are to benefit from this work,
somebody will have to propagate the changes into the cvs
tree.

Ditto for the new & improved location-in-air popup. I know
some people are using it ... but evidently only people who
live /beyond/ the bleeding edge. If this work is to benefit
people who live only /at/ the bleeding edge, let alone the
hoi polloi, somebody will have to propagate the new thing
into the cvs tree at some point.
