Issue with docstrings containing backslashes at the end of line

[etienneschalk]

Hi,

I am currently using pytest-accept for this issue of xarray: pydata/xarray#8690

I noticed a bug when a docstring contains a backslash at the end of line, then the lines are not properly replaced, an offset is introduced and it breaks the docstring

Example of a docstring that will surely fail on the xarray repo

Zoom on the section containing a backslash:

   combine_attrs : {"drop", "identical", "no_conflicts", "drop_conflicts", \
                     "override"} or callable, default: "override"

This docstring will make the auto-replacement fail. I attach here a screenshot to visually see the issue:

When removing the backslash, the pytest-accept tool successfully replace. Currently as a way to mitigate, I plan to remove all the backslashes at ends of line, running pytest-accept and then git revert the backslash removal.

Thanks!

Edit: the issue is already known and mentioned in the README

it reports line numbers incorrectly in some cases — two docstring lines separated with continuation character \ is counted as one, meaning this library will not have access to the correct line number for doctest inputs and outputs.

Yes, this is covered in the Readme...

If there are better approach, I'm very open to those...
