Re: [Bug-ed] [patch] proposal: adding '^' address

Well, accepting the '^' character as an address is not required by POSIX[1].

[1] http://pubs.opengroup.org/onlinepubs/9699919799/utilities/ed.html

Also, there are many incompatibilities among ed implementations, as 
stated in the 'rationale' section of the link above.

So I wonder what is the use of complicating the code, the testsuite and 
the documentation just to improve compatibility with other 
implementations on this, as your patch defines it, "historical and 
obscure feature of ed"?


Best regards,
Antonio.
