As of Emacs 25.1, `foo' is displayed as ‘foo’. This is controlled by
text-quoting-style, but curved quotes are the default.
This causes problems for docstrings that contain ' in code
snippets. Help buffers show e.g. (funcall 'foo) as (funcall ’foo),
which isn't legal elisp.
Instead, escape the quotes with \=. See substitute-command-keys for
the full docs on \= escaping.
This change addreses issue #123. The two new optional parameters to
`-fixfn' allow the caller to specify a custom equality test function,
such as an approximate comparison of floats, and a halt test function,
which can trigger a halt to the fixpoint iteration if it fails to
converge.
The default equality test remains `equal'. The default halt test is a
simple counter up to `-fixfn-max-iterations'. The counter is provided by
the new function `-counter'.
The revised tests illustrate the usage of the new parameters.
