All this talk about texdoc made me remember a reoccurring problem of mine. Until TL2020, `texdoc symbols` would give me the comprehensive list of symbols and having typed this very often, I'm pretty used to it.
But with TL2021 I now get
texdoc -l symbols
1 /usr/local/texlive/2021/texmf-dist/doc/fonts/newcomputermodern/newcm-unimath-symbols.pdf
= Math coverage and symbol comparison
2 /usr/local/texlive/2021/texmf-dist/doc/latex/comprehensive/symbols-a4.pdf
= The document (for A4 paper)
...
Is there any local configuration I could change to get `symbols-a4.pdf` if I type `texdoc symbols`?
