preproc.c: make extra sure we always have a null-terminated token
tok_set_text() and tok_set_text_free() take a length argument, which
could at least theoretically mean that we don't have a null-terminated
string. Directly enforce a null-terminated string in all cases.
In the future this means that it is legal to intentionally use these
functions to tokenize a substring.
