[PATCH v2 00/12] meson: wire up missing HTML documentation

Hi,

this patch series wires up missing HTML-based documentation with Meson. This includes a couple of missing manpages, the user manual as well as the random set of articles that we have. It also starts to generate the indices for API docs and howtos so that the result is a complete set of HTML docs, same as with our Makefile. It also fixes a couple of smaller issues I found while working on the series.

Notably missing yet is an integration with CI as well as sanity checks for any kind of missing docs in Meson. I'll work on this in a separate patch series once the initial CI integration as well as this patch series here have landed.

Further missing is the generation of both info pages and a user manual PDF. I couldn't find any users of these anywhere in downstream distros, so I decided to not care for now until somebody complains.

Changes in v2:

  - Change the base to 76cf4f61c8 (Merge https://github.com/j6t/git-gui,
    2024-12-26). This is done to fix conflicts with in-flight topics and
    to pull in the CI setup.
  - Fix a typo.
  - Include another commit to auto-detect missing manpages in Meson both
    via Meson itself, but also via our Makefile.
  - Make the equivalent check in t/Makefile work with Dash.
  - Link to v1: https://lore.kernel.org/r/20241213-b4-pks-meson-docs-v1-0-0c7895952cd3@pks.im

Thanks!

Patrick

         meson: generate HTML pages for all man page categories
     
         When generating HTML pages for our man pages we only generate them for
    -    category 1 in MEson, which are the pages corresponding to our built-in
    +    category 1 in Meson, which are the pages corresponding to our built-in
         commands. I cannot tell why I added this filter though: our Makefile
         installs all man pages, so a Meson-based build misses out on many of
         them.
