In general having such a feature would be nice, it's now bug
http://bugzilla.lyx.org/show_bug.cgi?id=4490
but only implementing this for this special case is not needed in my opion,
because:
Due to what I said in this post:

I put it in. Maybe you don't like this, but due to the reason above it _is_ safe. Of course I'll not
touch branch.

But we don't do this. In this case, the width reduction is necessary. But this has to be done in
general in LaTeX. When you want to have a box with exactly 1\columnwidth, you have to subtract the
box frame width because the frame is outside a box. That this is not automatically is a design bug
in LaTeX's box scheme and not ours. Whoever wrote this code in InsetBox.cpp did it correctly,
besides the bug with "1.0" instead of "1".

In the docs only the EmbeddedObjects and Extended manual refers to ERT when a feature is not
available with normal LyX methods. As they are extended detailed manuals this is acceptable. We
shouldn't hide special solutions from the users when LyX doesn't suport it without ERT. The concept
of the EmbeddedObjects manual is to explain everything that has been asked on the lyx-users list, if
possible.
But in this case the patch saves a lot of ERT as you can now use the box dialog and don't have to
create the whole box as ERT.
