Comment:

 I thought I'd need to backport this change, but it looks like stable-3.3
 is okay and by extension I assume the others are too.

 The output in 3.3 is


 {{{
 x="2.94485e-317" y="-1.14e-321";M 0 0 l 1 -1
 }}}


 I think the crash was introduced in master with the change of using
 string_buffer.  In master, I went with just skipping empties, so output is

 {{{
 M 0 0 l 1 -1
 }}}
