r"""Remove any common leading whitespace from every line in text.
This can be used to make triple-quoted strings line up with the left edge
of the display, while still presenting them in the source code in indented
form.
Note that tabs and spaces are both treated as whitespace, but they are not
equal: the lines ``" hello"`` and ``"\thello"`` are considered to have
no common leading whitespace.
If `skip_firstline` is True, the first line is separated from the rest of
the body. This helps with docstrings that follow `257`:pep:.
.. warning:: The `skip_firstline` argument is missing in standard library.
