If you do this then you cannot use the small editline library since
it does not have the using_history() and read_history() functions.
Do you really want to suck your whole history file into your
shell's address space?

Hi!
With the current version of rc I am not able to use the $history-
file with the readline-interface (i.e. CTRL-p, CTRL-r, ...).
The following patch forces rc to add the contents of the file
to the history list.
any comments?
