>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.
