code cool-down

[Bruno H. <br...@cl...>]

Hi,

Sam and I want to prepare a new release. For this reason, we now enter a
half code-freeze. At this point,

  - No changes of visible behaviour of clisp, except to fix regressions
    (vs. 2.33.2) and bugs.

The only commits that go in at this stage are:

  - fixes and implementation improvements for features that have been added
    since 2.33.2,
  - fixes for things that are unanimously recognized as bugs,
  - any kind of doc changes,
  - any kind of changes to the release infrastructure.

Bruno
