Change that 'verbose test' line to

	verbose test 1 = $(find .git/rebase-apply -name "000*" | wc -l)

i.e. losing the double-quotes around $().

By the way, thanks for a fine demonstration that the 'verbose test'
is not very useful.

This output

> command failed:  'test' '1' '=' '       1'

and that you said "on a mac", _I_ can immediately guess that there
is "wc -l" involved, because it has been a frequent source of
portability headache.

But "verbose" is not helping very much to show there is "wc -l";
unless the person debugging the output has a pretty good idea what
can go wrong, that is.
