ignoring made redundant by ignore-some-conditions

[paulapatience]

Alexandria's ignore-some-conditions is a superset of Serapeum's ignoring, where ignore-some-conditions can ignore several conditions.

I seem to remember reading about Serapeum's stance on API changes, but I cannot remember exactly where, or what the stance was (I believe it viewed them positively). With this in mind, I propose removing ignoring from Serapeum.

They're actually equipotent (you can always write (ignoring (or ....)).

Removing ignoring sounds like a good idea, but I'll need to put in due diligence to check if anyone is publicly using it.
