The docstring line width check ran before the {parameters} block was
substituted into the docstring, so parameter descriptions of any length
were accepted without a warning. This was a leftover of pythongh-150285, and
was easiest to miss for cloned functions, which inherit the parameter
descriptions of the function they clone.

Measure the rendered parameter description lines as part of the docstring
body, taking the indentation of the {parameters} marker into account, and
rewrap the 30 functions in the tree whose descriptions exceeded their
limit. The width warnings now also report the file they come from.

The issue lists 24 functions; the check reports 30. Three of the listed
functions (bytes.decode, bytearray.decode and winreg.ConnectRegistry) are
1 to 5 characters under their limit on this commit and are left unchanged.
