* Remove some tests we no longer need
* Delete blocks of redundant code
* Compress some tests together to simplify them
* Remove a little code for ancient linter versions
* Escape more executables we didn't escape before
* Rename a deno option that didn't match our conventions
ale#Escape function seems to prepend and append ' to the file name, which
are not present in the pydocstyle output. Having the parsing regexp match
the file name was overkill anyway, since there is an obvious 1:1
correspondence between the buffer number and the (potential) errors
reported by pydocstyle.
The linter can correctly parse pydocstyle output with any of the following
command-line options enabled: --explain, --source, --debug, and/or
--verbose
