BM's C++ version doesn't handle embedded quotes or single quotes either. 
Neither expand wildcards into sequences of filename arguments.

But you're right about 'length' which in the end was not used. It makes 
the C version even smaller without it.

I wasn't trying to match the OP's requirements, as I don't know what 
they are.

If this has to exactly match how the OS parses the command line into 
separate parameters, then that's likely to be a significantly more 
complex program, especially if it is to run on Linux.

There's probably no point in trying to create such program; you'd need 
to find a way of utilising the OS to do the work.

Note that I wasn't posting to solve the OP's problem, but as a 
counter-example to that C++ code which literally hurt my eyes to look at.
