| Yes, but I'm not sure how to go about it. Return NULL and let the caller
| deal with it? There's a general lack of error handling elsewhere too.

Something like that, I guess.

| 
| comes to mind ;)

we can't afford tripling the code size, but else I agree.

| Works for me. As I said, I went by a precedent in other places. I'm of a

| strchr(str, ' ')+1 instead though, that would get rid of the problem.

that could be useful, yes.
