/*
* editor -- fork editor to edit some text file
*
* Usage:
* i = editor(file, prompt);
* char *file, *prompt;
* int i;
*
* The editor() routine is used to fork the user's favorite editor.
* There is assumed to be an environment variable named "EDITOR" whose
* value is the name of the favored editor. If the EDITOR parameter is
* missing, some default (see DEFAULTED below) is assumed. The runp()
* routine is then used to find this editor on the searchlist specified
* by the PATH variable (or the default path). "file" is the name of
* the file to be edited and "prompt" is a string (of any length) which
* will be printed in a such a way that the user can see it at least at
* the start of the editing session. editor() returns the value of the
* runp() call.
