I knew it.  Changing the indentation is problematic.

This is caused by the new cl-indent.el file.  The modified indent
function disables the "with-*" thing by default, so with-gensyms is
indented like a function call.  If you load the macro definition, Lisp
will tell Emacs that once-only and with-gensyms are macros and how to
indent them.  You probably have slime-conservative-indentation=t, so
that SLIME ignores the indent hint for with-gensyms.  Setting it to
nil should help here.

We still have the problem that the macro definition must be loaded on
the Lisp side before it is indented correctly.  Perhaps the "with-*"
heuristic wasn't that bad after all.
