* editcmd.c (edit_save_file): fopen()+fwrite()+fclose() replaced
by open()+write()+close() to restore possibility to edit files
over Midnight Commander's VFSes
(edit_replace_cmd) [MIDNIGHT]: some more right algorithm to calculate
menu coordinates used. I don't like if menu hides replaced text.
(edit_goto_cmd): Memory leaking fixed when f is empty string
