Direct use of execute_command_line(3f) is appearing frequently in the code. Early in the design there was an intent that all external system calls be treated in a similiar manner by going through a wrapper routine. That wrapper routine was lacking documentation and, having grown organically it is not quiet intuitive. So this PR is nothing but documenation changes for the ford(1)=generated developer documentation. It includes a few minor corrections of other documentation but is primarily just documentation for the run(3f) procedure. It should cause no function changes, being just comments.
