"Issue #18408: PyObject_Str(), PyObject_Repr() and type_call() now fail with an
assertion error if they are called with an exception set (PyErr_Occurred()).

As PyEval_EvalFrameEx(), they may clear the current exception and so the caller
looses its exception."

 * Catch PyFile_WriteString() and PyFile_WriteObject() errors
 * Clear the current exception on _PyObject_GetAttrId() failure
 * Use PyUnicode_CompareWithASCIIString() and PyFile_WriteObject() instead of
   _PyUnicode_AsString() and strcmp() to avoid Unicode encoding error. stderr
   has a more tolerant error handler than utf-8/strict.

So it can be called even if an exception was raised

XMLParser configures expat to report attributes in a list (ordered_attributes),
so only _start_list is needed. Rename it to _start and kill _start.

Using ``method`` markup because the method is on a callback object, not an
explicitly documented method. :meth: markup creates links within the current
class which is incorrect.

In addition, indent the paragraph correctly.

Previously it generated them if they were given a value, but completely
ignored them if they were present in the string passed in to be parsed.  Now
if the flag appears on a cookie, the corresponding Morsel key will reference a
True value.  Other pre-existing behavior is retained in this maintenance
patch: if the source contains something like 'secure=foo', morsel['secure']
will return 'foo'.  Since such a value doesn't round trip and never did (and
would be a surprising occurrence) a subsequent non-bug-fix patch may change
this behavior.

Inspired by a patch from Julien Phalip, who reviewed this one.

Closes #18807: pyvenv now takes a --copies argument allowing copies instead of symlinks even where symlinks are available and the default.

The return value of close() is not always a toplevel element. It depends on
what the underlying target returns. By default, TreeBuilder returns the
toplevel document element.
