[PATCH 3/3] Constify two local variables.

[Daniel Shahaf <d.s@xxxxxxxxxxxxxxxxxx>]

---
I assume that v->pm->gsu.a->getfn() has no access to v->start and v->end, hence
changing the order is safe.

Are there any compilers that choke on 'char **const' (const pointer to pointer
to char)?

Cheers,

Daniel
