Allow tabs in DocTestParser about sybil

[cjw296]

43445d8 should resolve this, it'll be in a 2.0.1 release as soon as CI finishes running.

Can you share some examples of these non-Python blocks?
If they're not Python, how does doctest evaluate them?

Can you share some examples of these non-Python blocks?

Absolutely. I use the reStructuredText block to illustrate a text format that happens to use tabs. Here's an (actual) example (source):

To illustrate, let us consider the following CHAT utterance with its ``%mor``
tier::

    *XXA:	喂 遲 啲 去 唔 去 旅行 啊 ?
    %mor:	e|wai3 a|ci4 u|di1 v|heoi3 d|m4 v|heoi3 vn|leoi5hang4 y|aa3 ?

If they're not Python, how does doctest evaluate them?

I'm not sure -- I haven't dug into the internals of doctest / Sybil too much. For my use case. I'd want doctest / Sybil to simply ignore blocks like this, which the commit I referred to above would allow when allow_tabs=True in DocTestParser. Would there by any chance be a better way to accomplish this that I've missed?

Ah, so the problem is actually that doctest is spotting tabs in blocks it won't even match...

Thank you for the quick fix! I've just upgraded to Sybil 2.0.1 and my CI also passed as well. Thanks again!
