Type-o, change from[...] = 0 to fromb[...] = 0. The incorrect buffer

Browse Source 
was having its last element zero'd.  It turns out not to be a security
    hole or to have any real effect on the code because 'from' was previously
    pointing to a buffer of the same size as 'fromb', and the last
    element in fromb is already 0 anyway due to the use of sizeof(fromb)-1
    in the strncpy() call.  But I'm not pressing my luck so only the type-o
    is being fixed.
