- To determine the length of a constant string "foo", don't bother
with sizeof("foo")-1, please use strlen("foo") directly. gcc knows
strlen() anyway and turns it into a constant expression if possible.

+ strjoin() rather than asprintf(), as the latter is a lot
+ slower. This matters particularly in inner loops.
