>Description:
FreeBSD's sed(1) is incompatible with its handling of the G and H commands
because it does not explicitly append newlines when appending a line of input,
it relies on them just "popping up" because we use fgetln to get lines of
input. This relates to appending the hold or pattern space.
>How-To-Repeat:
(echo 1; echo 2; echo 3; echo 4) | sed '1,2H;2,3G'
with our sed(1), and GNU's, and SysV's.
>Fix:
Create a function to append a line to a given space, instead of using cspace,
and have it do the correct thing. Possibly, NUL-terminate at the newline when
using fgetln(3) at mf_gets.
