2 months ago - When testing previous commit I discovered that this version of ed incorrectly accepts "0,1w file.mp3" command
- Address range 0-1 is not valid because lines count from 1
- Error was also not raised for "0w file.mp3", i.e. single-address mode
- Follow OpenBSD and GNU versions by printing invalid-address error
- Technically, the command ",1w file" is valid; this is interpreted as implied range of "1,1" which is the same as just "1w"
