Each libretro profile records version_basis and core_version is read
there at its pin. snes9x states 1.63 in snes9x.h, nestopia 2.0.0, mgba
0.11.0, vice 3.10, atari800's libretro tree 7.0.0. Cores whose build
takes its version from git carry the nearest tag in describe form
(flycast v2.7-90-ge88b0ce, ppsspp, duckstation, gearcoleco), placeholders
copied from .info files (Git, SVN) are replaced by the code's statement,
and a code that states none is null with kind none.
One run of profile_sync --all --rebase-refs --fresh. Every guard held:
no ref to review, no prose left under an older pin, no file name or hash
literal gained in a cited file since the pin, no built_by pin and no pin
keyed by build mode. The site's record of cited source paths is rebuilt
with them.
