skip_file ignored when on the first docstring line

[romaingz]

This does not occur on version 5.9.3.

Since version 5.10.0, the following skip_file directive is ignored:

"""isort:skip_file"""

This is also ignored:

"""isort:skip_file

some other comment.
"""

It needs to be on a new line:

"""
isort:skip_file
"""

skip_file in a comment is also ignored.

#  isort:skip_file

[ahopkins]

FWIW, this is also ignored, new line with whitespace.

"""
   isort:skip_file
"""

Here's an example of 5.10.0 ignoring directives (unless there's some intentional change I'm missing?): pydata/xarray#5949

Sorry for the noise! This should be fixed in https://github.com/PyCQA/isort/releases/tag/5.10.1, a contribution meant to avoid false flagging of non-comment isort: skip-files, was to narrow and has been reverted. In the meantime additional test cases will be added to catch this going forward.

Thanks!
