[hackers] [PATCH 6/6] ed: Don't undo commands in sigint

[Roberto E. Vargas Caballero]

If newcmd is 0 then error() undo all the modifications
that happened since the last command, but this is  not
what POSIX mandates:

SIGINT  The ed utility shall interrupt its current activity, write the
        string "?\n" to standard output, and return to command mode
        (see the EXTENDED DESCRIPTION section).
