Removing a now unneeded function, as nothing can break out of do_prompt()

* src/prompt.c (get_prompt_string): Preserve the cursor position on
the statusbar when just toggling a setting or making an excursion to
the file browser. This fixes Savannah bug #46945.
* src/prompt.c (do_prompt_abort): Remove this unneeded function, as
nothing can break out of do_prompt(), not a SIGWINCH either.
* src/prompt.c (get_prompt_string): Delete code that is dead now.
