[TxMt] Re: sudden latex tidy and latex compiling errors

[Anthony V. Pulido]

Hi René, I'm so relieved that latex tidy is coming back. No worry! Please
take the time you need.

I'll see if I can produce a sample document to reproduce the other error,
and I'll see about submitting comments to the github page on latexindent.

Thanks again!

Best wishes,

Anthony
