call-process-region:
Send text from START to END to a process running PROGRAM.
Delete the text if DELETE is non-nil.
Put output in BUFFER, before point.  nil => discard it, t => current buffer.
Sixth arg DISPLAY non-nil means redisplay buffer as output is inserted.
Remaining args are passed to PROGRAM at startup as command args.
This function normally waits for the process to terminate;
if you quit, the process is killed.
-----------------------------------------------------------------------------
The documentation above should mention the possibility of BUFFER being 0, as
the documentation below does.

call-process:
Call PROGRAM in separate process.
Program's input comes from file INFILE (nil means /dev/null).
Insert output in BUFFER before point; t means current buffer;
 nil for BUFFER means discard it; 0 means discard and don't wait.
Fourth arg DISPLAY non-nil means redisplay buffer as output is inserted.
Remaining arguments are strings passed as command arguments to PROGRAM.
This function waits for PROGRAM to terminate;
if you quit, the process is killed.
