Hmph, just when I thought I knew about all of the weird shell quirks. :)

I am not convinced this isn't a violation of POSIX (which specifies that
field splitting is done on the results of parameter expansions outside
of double-quotes). But whether it is or not, we have to live with it.

For my own curiosity, what does:

  foo='with space'
  printf "%s\n" ${foo:+first "$foo"}

print? That is, are the double-quotes even doing anything on such a
shell? On bash and dash, it prints:

  first
  with space

which is what I would expect. So does "ash" (0.5.7, packaged for
Debian), which is what I _thought_ FreeBSD's shell was based on. But
clearly there is some divergence.

I guess they are getting eaten by your shell, otherwise we would pass
them along to git in the test script, which would complain.

Patch itself looks obviously correct.
