that makes sense.  but why would appending to an archive as the result
of bulk archiving lag?  if the problem is large archive files, which
i'd bet is the case for a lot of users and not just me, then could org
in principle be changed so that all it does is append?  thus not lag?
like, build the entry in a temporary buffer?

as i see it, having more than one archive file per org file is good
for speed, but doesn't work in existing org, because iirc e.g. v A in
the agenda goes org agenda file -> corresponding archive file and will
miss the archive files that do not have a corresponding org file with
exactly the same basename sans extension.

i'd be ok with released org either allowing hte user to make
year-based archives by having all of org recognize them, or my just
append thing above.  maybe i am missing something.

this implies to me e.g. year-based archives, which would fail the v A
test iiuc.  thus needed extra code.

i look forward to this filtering down to maint.  :]  [i used to follow
master but too much for me now for health reasons.]

good idea.  my included-by-agenda archive files do seem to be in
showeveryting mode already for some reason.  but perhaps not when bulk
archiving.

would it be a silly idea for an fr that org make this an option for
bulk archiving?  hmm or for archive files in general?

if so, then i figure it's a one-time thing per file so no big deal.
but thanks for hte font lock stuff i didnt' know about.

firefox find does not seem to find it.
