docs: pdfdocs: Prevent column squeezing by tabulary
Setting a reasonable width to \tymin prevents column squeezing by tabulary. Width of 20em works well in almost all the tables still in the ascii-art format. Excerpt from tabulary package documentation at [1]: To stop very narrow columns being too 'squeezed' by this process any columns that are narrower than \tymin are set to their natural width. [1]: https://mirrors.ctan.org/macros/latex/contrib/tabulary/tabulary.pdf Note: Sphinx has its own default value of \tymin set in sphinxlatextables.sty (Sphinx 4.0.2) and sphinxmulticell.sty (Sphinx 2.4.4) as follows: \setlength{\tymin}{3\fontcharwd\font`0 } , which is not sufficient for kernel-doc. Tested against Sphinx versions 2.4.4 and 4.0.2.
