Bug in GNU ed 0.2

[DervishD]

    Hi all :))

    When GNU ed is started interactively and the first command is 'H'
or 'h', it prints garbage. IMHO this is caused because 'errmsg' is
used uninitialized after it is allocated.

    Just do a 'calloc' instead when allocating buffers (I haven't
read all the sources, but I think that this can apply to all other
allocated buffers), or set the first char of 'errmsg' to '\0', or use
memset, etc... There are plenty of solutions :))

    Thanks for making 'ed' free software :)
