commit: remove special handling of IOError (actually dead code)
In the past, IOError was used to mark a file as removed. The differentiation
between OSError and IOError in this place was introduced in
e553a425751d, to
avoid that “normal” OSErrors / IOErrors accidentally mark files as removed.
This weird internal API was removed in
650b5b6e75ed. It seems like that
changeset should have removed the differentiation, at least I don’t see any
reason for keeping it.
On Python 3, OSError and IOError are aliased. Therefore the removed code was
actually dead.
"""
List-valued configuration keys have an ad-hoc microsyntax. From `hg help config`:
> List values are separated by whitespace or comma, except when values are
> placed in double quotation marks:
>
> allow_read = "John Doe, PhD", brian, betty
>
> Quotation marks can be escaped by prefixing them with a backslash. Only
> quotation marks at the beginning of a word is counted as a quotation
> (e.g., ``foo"bar baz`` is the list of ``foo"bar`` and ``baz``).
That help documentation is fairly light on details, the actual parser has many
other edge cases. This test tries to cover them.
