Currently, execlog searches for a space separator between the instruction mnemonic and operands, but some disassemblers, e.g. Alpha's, use a tab separator instead; this results in a null pointer being passed as the haystack in g_strstr during a subsequent register search, i.e. undefined behavior, because of a missing null check. This patch adds tab to the separator search and a null check on the result. Also, an affected pointer is changed to const. Lastly, a break statement was added to immediately terminate the register search when a user-requested register is found in the current instruction as a trivial optimization, because searching for the remaining requested registers is unnecessary once one is found.
