* wordexp must set the we_offs entries of we_wordv to null pointersRich Felker2012-04-161-0/+4
* fix crash in wordfree if we_offs is not initialized by the caller•••I'm not sure if it's legal for wordexp to modify this field, but this is the only easy/straightforward fix, and applications should not care. if it's an issue, i can work out a different (but more complex) solution later.

* wordexp cannot use we_offs unless WRDE_DOOFFS flag is set•••previously, a potentially-indeterminate value from we_offs was being used, resulting in wrong we_wordc and subsequent crashes in the caller. Rich Felker2011-06-251-1/+2
