Hi @tech,
I remark that ed(1) do not support adress ranges which begin with
comma or semicolon, for example ",10p" which is equivalent to "1,10p" or
"; +10p" which is equivalent to ".;+10p". These adress ranges are
specified by Open Group Base Specifications Issue 6 (IEEE Std 1003.1,
2004 Edition) (in fact, there are also adress ranges like "10," which
is equivalent to "10,10" but they seem useless to me...).
I would suggest this diff to add support for these adress ranges.
