Proposal: hide unknown \commands

[StevenClontz]

(please close with my apologies if this has been addressed since version 3.61.0)

The cause of TeamBasedInquiryLearning/checkit-tbil-la#46 is that it uses software that relies on this package, and https://github.com/roniemartinez/latex2mathml/blob/master/latex2mathml/commands.py#L23 seems to indicate that \middle is unsupported as of the current version 3.64.0.

I don't know how difficult supporting \middle is, but would it make sense to hide unknown commands rather than output them as text? In the case of decorative commands like this, things might look "good enough", but maybe this is worse for a command intended to output something on its own.

@StevenClontz \middle is now added in https://github.com/roniemartinez/latex2mathml/releases/tag/3.65.0

As for hiding unknown commands, I personally think this is not a good idea as this is an easy way to hide bugs.

I can add an ENV flag for muting, for example. What do you think?

That makes sense to me.
