sbcl-1.3.13 released

Dear all,

I have released sbcl-1.3.13, and uploaded source and an x86-64/linux
binary to sourceforge; some other binaries will no doubt trickle in over
the next few days.  The changes in this release are appended below; I
expect to make another release earlier than usual in the month of
January, to harmonize better with Debian's freeze period.

Best wishes for the new year,

Christophe
