Re: [Bug-ed] Change in `s/xyz` 1.13 -> 1.14.2 ?

[Steven Terpe]

The long error is ‘Missing Pattern Delimiter’.  Which I get, but I don’t see 
this as an improvement, because what I want to do by issuing the command 
`s/xyz` is a given.  Plus there is issue of backwards compatibility of ed 
scripts which could now be broken by this change as well as an unnecessary 
deviation from the common behavior of BSD ed and previous versions of GNU ed.
