Johannes suggested in
https://lore.kernel.org/git/nycvar.QRO.7.76.6.2107052336480.8230@tvgsbejvaqbjf.bet/
that (if I understand that correctly, and I just skimmed the linked isse
some days ago), that even if such a refactoring was done these two
functions are solving subtly different problems, or something. I.e. we
couldn't use it for daemonize().

Which I'd say is interesting for the code comments/commit message at
least, i.e. how they're solving subtly different problems (not being
able to run this & not being able to test on Windows I haven't poked at
it myself).

Fair enough, And I think replied-to above.

FWIW what I was noting here & elsewhere is that yes, you need to ifdef
some of it, but the code you're proposing to add here is using a
different pattern than the one generally preferred in this codebase.

I.e. check out how we do it for threading, we intentionally compile the
"if (thread) {code}" clauses on platforms we know don't have threading,
ditto the code around PCRE in grep.c. 

Similarly, here in e.g. spawn_background_fsmonitor_daemon just the
GetModuleFileNameA() and mingw_spawnvpe() are Windows-specifics (and
could be calls to some helper that *is* ifdef'd).

In this case it's not a big deal, but as a general pattern it helps to
e.g. avoid subtle syntax errors in nested ifdefs and the like, and
generally encourages keeping the ifdef'd code as small as possible.

Will this code behave correctly if the daemon we start is signalled per
the WIFSIGNALED() cases the code this is derived handles, but this does
not?

But sure, I just meant to point out that the flip side to "destabilize
all existing callers" is reviewing new code that may be subtly buggy,
and those subtle bugs (if any) would be smoked out if we were forced to
extend run-command.c, i.e. to use whatever feature(s) this needs for all
existing callers.
