fixed invalid memory access when executing the F< command (but only when jumping to the beginning of the macro)
* I am not sure whether this feature is really that useful... * teco_machine_main_t::macro_pc is now pointing to the __next__ character to execute, therefore it's easier to manipulate by flow control commands. Also, it can now be unsigned (gsize) like all other program counters. * Detected thanks to running the testsuite under Valgrind.
