Oops, yeah, sorry.

Just for the record:  I pointed this out when the patch was discussed
on the list, and proposed a better solution:

  http://thread.gmane.org/gmane.comp.version-control.git/184229/focus=184290

but apparently only after that patch was already merged.  Since we are
in -rc phase, this patch below chooses the less intrusive solution
(i.e. it declares the variable as local instead of eliminating it by
using the command substitution as here string).
