parse: use "0<" instead of "0 <"
...
As I wrote in my "Clarify signed-ness" commit, "0 <" is broken.
Also, made this unit a bit more compact. The RC2014 stage1 can
really use some breathing room...

recipes/rc2014: stage1 is too big! saving some space
...
stripfc requires 2 spaces before "(" to strip a comment. This was
a low hanging fruit for me to get stage1.bin under the 8K line.
That thing is getting tight...
