process-echo: preference buffer-specific variable

Default value: 2

This variable controls how Epsilon handles character echoing in process buffers. Sometimes changing this setting produces better results with particular replacement command processors (shells). A value of 0 makes Epsilon suppress echoing, assuming the subprocess will do it. A value of 1 forces it on, 2 makes Epsilon select an appropriate behavior in a static fashion, and 3 makes Epsilon select an appropriate behavior dynamically, each time it sends input to a process. (Under Unix, 2 and 3 act the same as 1.)

Adding 4 to one of the above values changes which line termination character Epsilon sends, from its usual choice of <Return> or <Newline> (depending on the platform) to the other one.

Adding 8 makes the filter-region command run the process synchronously; by default it runs synchronously only when replacing text in a buffer, not when sending output to a new buffer.
