This patch changes doctest's test finder to include all files in the nutils
directory, rather than the ones listed in nutils.__all__ which is due to be
removed. The change includes a modified version of DocTestFinder to fix a bug
triggered by the SI module (formerly untested) and for which a PR is created
for cpython (python/cpython#107716). The patch also
includes a small fix in SI's documentation.

…7716)

This patch escapes the class name before embedding it in the regular expression
for `pat` in `doctest.DocTestFinder._find_lineno`. While class names do not
ordinarily contain special characters, it is possible to encounter these when a
class is created dynamically. Escaping the name will correctly return `None` in
this scenario, rather than potentially matching a different class or raising
`re.error` depending on the symbols used.
