This PR updates coverage from 7.6.1 to 7.6.4.

Changelog

7.6.4

--------------------------

- fix: multi-line ``with`` statements could cause contained branches to be
incorrectly marked as missing (`issue 1880`_).  This is now fixed.

.. _issue 1880: https://github.com/nedbat/coveragepy/issues/1880


.. _changes_7-6-3:

7.6.3

--------------------------

- Fix: nested context managers could incorrectly be analyzed to flag a missing
branch on the last context manager, as described in `issue 1876`_.  This is
now fixed.

- Fix: the missing branch message about not exiting a module had an extra
"didn't," as described in `issue 1873`_.  This is now fixed.

.. _issue 1876: https://github.com/nedbat/coveragepy/issues/1876


.. _changes_7-6-2:

7.6.2

--------------------------

- Dropped support for Python 3.8 and PyPy 3.8.

- Fix: a final wildcard match/case clause assigning to a name (``case _ as
value``) was incorrectly marked as a missing branch.  This is now fixed,
closing `issue 1860`_.

- Fewer things are considered branches now. Lambdas, comprehensions, and
generator expressions are no longer marked as missing branches if they don't
complete execution.  Closes `issue 1852`_.

- Fix: the HTML report didn't properly show multi-line f-strings that end with
a backslash continuation.  This is now fixed, closing `issue 1836`_, thanks
to `LiuYinCarl and Marco Ricci <pull 1838_>`_.

- Fix: the LCOV report now has correct line numbers (fixing `issue 1846`_) and
better branch descriptions for BRDA records (fixing `issue 1850`_).  There
are other changes to lcov also, including a new configuration option
:ref:`line_checksums <config_lcov_line_checksums>` to control whether line
checksums are included in the lcov report.  The default is false. To keep
checksums set it to true.  All this work is thanks to Zack Weinberg
(`pull 1849`_ and `pull 1851`_).

- Fixed the docs for multi-line regex exclusions, closing `issue 1863`_.

- Fixed a potential crash in the C tracer, closing `issue 1835`_, thanks to
`Jan Kühle <pull 1843_>`_.
