Patch from NetBSD
sed functions 'a' and 'i' discard leading white space of the inserted/appended
line(s) of text.
This comes from NetBSD's PR/49872
I have confirmed their test on FreeBSD:
(old sed)
pfg@gorilon:~/test % echo | sed -f test.sed | vis -l
test 2 \$
\$
test 1 \$
pfg@gorilon:~/test % vis -l < test.sed
a\134\$
test 1 \$
i\134\$
test 2 \$
\$
(new sed)
pfg@gorilon:~/test % echo | sed -f test.sed | vis -l
test 2 \$
\$
test 1 \$
______
New behavior would be similar to GNU sed.
