[PATCH 1/2] load_dfa: Fix size of buffer equiv

[Jörg Sommer <joerg@xxxxxxxxxxxx>]

The buffer equiv must have UCHAR_MAX + 1 elements to save all the
elements as in Highlight.equiv. Because the check for the upper boundary
was on <= UCHAR_MAX the (UCHAR_MAX+1)th element was touched which caused
a stack corruption and an abort if jed was compiled with -fstack-protect.
