[PATCH] shortlog: don't set after_subject to an empty string

The string after_subject is added to a strbuf by pp_title_line() if
it's not NULL.  Adding an empty string has the same effect as not
adding anything, but the latter is easier, so don't bother changing
the context member from NULL to "".
