For me (and others), LyX is also a way to learn LaTeX. Typing LaTeX macros
in LyX that work in LyX but not in TeX is counter-productive in this case.

However, this is inconsistent:
* if I insert a literal degree-sign from the keyboard into mathed, LyX
wraps it in \text while inserting,
* if I write \textdegree in mathed, LyX wraps it when exporting (after your
patch).

Silent "helpers" all too often stay in the way when doing something the
original author did not think of...

Really? With an integral in "mathed text" I got:
* in the source pane: $A=\text{\ensuremath{\int}d}x$
* copying the complete mathbox: A=\text{\ensuremath{\int}d}x
* copying from inside the math-box: \text{\int d}x

At least, this will stop the silent wrapping of text-mode macros in
\ensuremath if correctly used...
