alm 9380925b08 Added a line-addressing test so this isn't overlooked again.
Added BACKWARDS directive to Makefile for compatibility.
Completely changed the name space as per FSF's request.
Fixed a line-addressing bug introduced by previous `fix', i.e.,
space preceding a digit acts a plus (+) operator, as in `1 1' == `2',
and a plus operator by itself acts as +1, but a space by itself
should not equal a plus operator, i.e., `1 ' != `1+' == `2'.

ed is an 8-bit-clean, POSIX-compliant line editor.  It should work with
any regular expression package that conforms to the POSIX interface
standard, such as GNU regex(3).

If reliable signals are supported (e.g., POSIX sigaction(2)), it should
compile with little trouble.  Otherwise, the macros SPL1() and SPL0()
should be redefined to disable interrupts.

The following compiler directives are recognized:
DES		- use to add encryption support (requires crypt(3))
NO_REALLOC_NULL	- use if realloc(3) does not accept a NULL pointer
BACKWARDS	- use for backwards compatibility
EX_BANG		- use to support ex-style ! (bang) command.

The file `POSIX' describes extensions to and deviations from the POSIX
standard.

The ./test directory contains regression tests for ed. The README
file in that directory explains how to run these.

"Software Tools in Pascal," Addison-Wesley, 1981.
