bundle: fix exclusion of annotated tags

In commit c9a42c4 (bundle: allow rev-list options to exclude annotated
tags, 2009-01-02), support for excluding annotated tags outside the
specified date range was added. However, the wrong order of parameters
was chosen when calling memchr().

Fix this by swapping the character to search for with the maximum length
parameter.  Also cover this behavior with an additional test.
