* libc/posix/wordfree.c (wordfree): The wrong words are freed
when WRDE_DOOFFS is in use. Restructure the code so that the memory
needed to be freed is instead kept in an internal linked list...
* libc/posix/wordexp2.h: ...as defined here...
* libc/posix/wordexp.c (wordexp): ...and build this internal
linked list here, avoiding wasteful strdup calls in the process.
