Sören Tempel bfd8738154 ed: add support for -p command-line option as mandated by POSIX

The POSIX.1-2008 specification of ed(1) mandates two command-line
options: -p (for specifying a prompt string) and -s (to suppress writing
of byte counts). This commit adds support for the former. Furthermore,
it also changes the default prompt string to an empty string (instead
of ": ") since this is also mandated by POSIX:

	-p string Use string as the prompt string when in command mode.
	          By default, there shall be no prompt string.
