Commit0709e4be8b(Use standalone code paths by default, 2025-10-26) mainly wanted to embed internal functions to unbreak upgrade scenarios. Embedding man pages in CMake has small-ish disadvantages: 1. extra space usage 2. less discoverability 3. a "cyclic" dependency: 1. "sphinx-docs" depends on "fish_indent" 2. "fish_indent" via "crates/build-man-pages" depends on "doc_src/". So every "touch doc_src/foo.rst && ninja -Cbuild sphinx-docs" re-builds fish, just to re-run sphinx-build. The significant one is number 3. It can be worked around by running sphinx-build with stale "fish_indent" but I don't think we want to do that. Let's backtrack a little by stopping embedding man pages in CMake builds; use the on-disk man pages (which we still install). The remaining "regression" from0709e4be8bis that "ninja -Cbuild fish" needs to rebuild whenever anything in "share/" changes. I don't know if that's also annoying? Since man pages for "build/fish" are not in share/, expose the exact path as $__fish_man_dir.
