Hi,
this patch was present in msysgit from Mar 2012.
Do you like it?
I'm sorry, there is no author signoff; is the patch small enough?
It needs an explanation in the commit message, too. As Felipe noted, I
do not think it would help with ambiguity, but it should not hurt, and
is a reasonable defensive thing to do (but I did not think about it too
long, so maybe Sverre has an example that needs it).

It would be nice if this were an argv_array so we would not have to
worry about managing the array size. This is one of several spots that
leaks array memory that I have been meaning to fix.
I just posted a series that addresses those leaks and converts this
site. I do not want to hold your patch hostage to my series, but
depending on the review on my series, you may want to re-roll this on
top; you would drop the line above, and change:
+ fastexport-argv[argc++] = --;
to:
argv_array_push(fastexport-args, --);
