This file is part of GNU Emacs.
Fourth arg DISPLAY non-nil means redisplay buffer as output is inserted.
Remaining arguments are strings passed as command arguments to PROGRAM.
+If executable PROGRAM can't be found as an executable, `call-process'
+signals a Lisp error. `call-process' reports errors in execution of
+the program only through its return and output.
+
If BUFFER is 0, `call-process' returns immediately with value nil.
Otherwise it waits for PROGRAM to terminate
and returns a numeric exit status or a signal description string.
