inhibit some immediate editing commands after ^Q/^R string building constructs

* This allows you to type ^Q^U (which would otherwise rub out the entire argument)
  and ^Q^W (which would otherwise rub out the ^Q).
* ^Q^U coincidentally worked previously since the teco_state_stringbuilding_escaped
  state would default to teco_state_process_edit_cmd().
  But it's better to make this feauture explicit.
* This finally makes it possible to insert the ^W (23) char into a buffer.
  In interactive mode, you can still only type Caret+W as a string building construct.
* ^G could also be inhibited after ^Q, but the control char is not used anywhere yet,
  so there is no point in doing that.
