I wasn't saying you should modify the text to be inserted in-place,
I'm saying stop the emission of the current insert_text signal, and
emit a second insert_text signal with the text you want (emit the
second signal by calling gtk_editable_insert_text() or whatever it's
called).

For the infinite loop you can either set a global variable, or use
the gtk_signal_handlers_block_*() functions.
