[PATCH v2] meson: regenerate config-list.h when Documentation changes

Message-ID: <c9ae171eed6bd5b0fa6671b10a5ad0da024f36d0.1770649805.git.ben.knoble+github@gmail.com>
In-Reply-To: <20260207215924.28863-2-ben.knoble+github@gmail.com>

The Meson-based build doesn't know when to rebuild config-list.h, so the header is sometimes stale.

For example, an old build directory might have config-list.h from before 4173df5187 (submodule: introduce extensions.submodulePathConfig, 2026-01-12), which added submodule.<name>.gitdir to the list. Without it, t9902-completion.sh fails. Regenerating the config-list.h artifact from sources fixes the artifact and the test.

Teach the meson build to depend on the Documentation files that generate-configlist.sh reads by having it use the output of generate-configlist-deps.sh as a list of dependency files, since Meson does not have (or want) builtin support for globbing like Make.

Notes (benknoble/commits):
    I considered having generate-configlist.sh write its own dependency
    list, which Meson also supports… idk though. Input welcome :)

    This was also built on top of commits [1] on next, but should not depend on
    them despite what base-commit and prerequisite-patch-id say. Indeed, it
    applies cleanly to master @ 3e0db84c88 (Start 2.54 cycle, 2026-02-05).
