Apologies.  It is indeed Linux's thing.  When one types C-M-g, the Linux
keyboard driver produces the two character sequence 0x19,0x07, i.e.  ESC
C-g.  Presumably under X, this gets converted into C-M-g before Emacs
sees it.

It would be unreasonable in the extreme to expect Emacs to distinguish
between a user typing ESC followed by C-g, and her typing C-M-g.

I have solved the problem for me personally by remapping my keyboard such
that C-M-g now generates "esc [ 3 > g".  For this, I have a handling
function in the function-key-map.

Many thanks for prodding me to look at this more closely!
