Subject: base/dispatch.c: Stop parsing the auxiliary vector when we hit `AT_NULL'.
X-Git-Tag: 2.2.3~1^2~21

base/dispatch.c: Stop parsing the auxiliary vector when we hit `AT_NULL'.

This doesn't seem too dreadful so far (partly because nothing is using
this machinery for something important, and partly because we're parsing
the vector from a file with known length), but fix it anyway.
