By the way, the way we spell these two entities in the glossary is
"pack" - that which holds collection of objects tightly packed
"pack index" - that which allows a random access into a "pack"
We may want to do two things:
(1) add "packfile" as a synonym to the former; I think the origin
of "pack file" is that it would clarify which one we refer to
it as an on-disk entity when contrasting a "pack" and its
associated "pack index", and I even suspect that originally we
spelled it as two words, later contracted with dash (as seen in
the pack-heuristics irc lecture given by Linus).
(2) describe "pack bitmap", which came long after the original
glossary entries are made.
And if we are going that route, we should fix the SYNOPSIS sections
and usage[] strings of "index-pack" and "unpack-objects" where we
say these commands read from "<pack-file>" (we now read from
"<packfile>").
I am undecided if we want to touch Documentation/technical/. The
irc lecture in pack-heuristics.txt is a historical recording and it
may be OK to keep it as it is. pack-protocol.txt consistently uses
"packfile" in prose and uses "pack-file" in EBNF. From a quick
re-reading of the document, I think it is OK to use "packfile"
throughout there.
One related thing is that there are few mentions of "idx file" to
refer to "pack index" (e.g. show-index and verify-pack documentation
pages); I think this was an attempt to disambiguate "pack index"
from "the Index", but as long as we spell it "pack index", I think
it should be OK, so while we are at it we may want to fix them. We
can leave "pack .idx file" as-is, but rewriting it to "pack index
file" or just "pack index" may be OK as long as it is clear from the
context.
"git show-index" has this in SYNOPSIS:
'git show-index' < idx-file
It probably should become
'git show-index' < <pack-index>
