ebaa79f (Make report() from usage.c public as vreportf() and use it.,
2010-03-06) changed fast-import's die_nicely() to use vreportf().
This requires some more care though. First it forgot that we also
need to reformat the message for the crash report. Second, vreportf()
uses vsnprintf(), which does not call va_end(). This leaves the
va_list passed to it in an undefined state. Therefore we need to make
a copy of this va_list so that we can reuse it.

Another valgrind catch. I think that'll be the last one for today.
Thanks for your attention.
