I just noticed you were the original reporter there, too. So I guess it
compelled you, too. ;)

If we do want to keep the other implementations around, another thing
that might be worth doing is to teach t0013 to complain when the
collision-detecting sha1 is not in use (i.e., rather than auto-skipping
when built without DC_SHA1, require the user to set a special
NO_REALLY_I_CHOOSE_NOT_TO_USE_DC_SHA1_AND_AM_AWARE_OF_THE_IMPLICATIONS
variable). That would provide a cross-check on the build flags.
