[MacTeX] LaTeX format not rebuilt after package update

[Karl Berry]

Hi Andreas,

    My question is: How can I re-configure MacTeX/BasicTeX to follow suit?

tlmgr option formats 1

tlmgr option show
will report all options and their values.

tlmgr option --help
will give a more verbose description, same as what's online at
https://tug.org/texlive/doc/tlmgr.html#option

(I guess I should change the description of "formats" to say
"on installation or update".) --best, karl.
