1.3.59.uu2.jcn1
===============

* Fixed scm_un/protect_object for guile-1.3.4 and 1.3.5 snapshots,
  in the process reduced number of protect/unprotect calls.  With
  guile-1.3.5 snapshot, memory usage has decreased by 1/5th, now
  just 10% above the 1.2 level.  Also, Lily's a bit faster.

* Fixed make diff bug in stepmake to be able to make this diff :-)
