This is the commit (from 2011!) where I added this code:

My guess is that I did not want multiple newlines to collapse in t-vim, so
I had redefined \activeendoflinetoken to {\strut\par}. The offending
lines are copied from catc-ini.mkiv from the same time:

https://github.com/contextgarden/context-mirror/blob/5056d7a854142aa63032b0a3ca4d41c496e41faf/tex/context/base/catc-ini.mkiv

to make sure that I use the same syntax for MkII and MkIV.

A couple of years after that I split the MkII and MkIV code into separate
files, but I never touched the catcode part (because it was working).

I cannot test the latest beta right now; I'll test it on Monday. In the
meanwhile, what is the current recommended method to alter the way literal
newlines and tabs are shown.
