The implementation of digit-separating single-quotes introduced a
note-worthy regression: the change of a character literal with a
digit would splice the digit and the closing single-quote. For
example, the change from 'a' to '2' is now tokenized as
'[-a'-]{+2'+} instead of '[-a-]{+2+}'.
The options to fix the regression are:
- Tighten the regular expression such that the single-quote can only
occur between digits (that would match the official syntax).
- Remove support for digit separators.
I chose to remove support, because
- I have not seen a lot of code make use of digit separators.
- If code does use digit separators, then the numbers are typically
long. If a change in one of the segments occurs, it is actually
better visible if only that segment is highlighted as the word
that changed instead of the whole long number.
This choice does introduce another minor regression, though, which
is highlighted in the test case: when a change occurs in the second
or later segment of a hexadecimal number where the segment begins
with a digit, but also has letters, the segment is mistaken as
consisting of a number and an identifier. I can live with that.

Use a ref_sorting_release() in branch.c to free the memory from the
ref_sorting_options(). This plugs the final in-tree memory leak of
that API.
In the preceding commit the "sorting" variable was left in the
cmd_branch() scope, even though that wasn't needed anymore. Move it to
the "else if (list)" scope instead. We can also move the "struct
string_list" only used for that branch to be declared in that block
That "struct ref_sorting" does not need to be "static" (and isn't
re-used). The "ref_sorting_options()" will return a valid one, we

static was another artifact of the pre-image of the preceding commit.

When a transport helper pushes via send-pack, it passes --helper-status
to get a machine-readable status back for each ref. The previous commit
taught the send-pack code to hand back "error expecting report" if the
server did not send us the proper ref-status. And that's enough to cause
us to recognize that an error occurred for the ref and print something
sensible in our final status table.
But we do interpret these messages on the remote-helper side to turn
them back into REF_STATUS_* enum values. Recognizing this token to turn
it back into REF_STATUS_EXPECTING_REPORT has two advantages:
1. We now print exactly the same message in the human-readable (and
machine-readable --porcelain) output for this situation whether the
transport went through a helper (e.g., http) or not (e.g., ssh).
2. If any code in the helper really cares about distinguishing
EXPECT_REPORT from more generic error conditions, it could now do
so. I didn't find any, so this is mostly future-proofing.
So this is mostly cosmetic for now, but it seems like the
least-surprising thing for the transport-helper code to be doing.

When pushing to a server which erroneously omits the final ref-status
report, the client side should complain about the refs for which we
didn't receive the status (because we can't just assume they were
updated). This works over most transports like ssh, but for http we'll
print a very misleading "Everything up-to-date".
It works for ssh because send-pack internally sets the status of each
ref to REF_STATUS_EXPECTING_REPORT, and then if the server doesn't tell
us about a particular ref, it will stay at that value. When we print the
final status table, we'll see that we're still on EXPECTING_REPORT and
complain then.
But for http, we go through remote-curl, which invokes send-pack with
"--stateless-rpc --helper-status". The latter option causes send-pack to
return a machine-readable list of ref statuses to the remote helper. But
ever since its inception in de1a2fdd38 (Smart push over HTTP: client
side, 2009-10-30), the send-pack code has simply omitted mention of any
ref which ended up in EXPECTING_REPORT.
In the remote helper, we then take the absence of any status report
from send-pack to mean that the ref was not even something we tried to
send, and thus it prints "Everything up-to-date". Fortunately it does
detect the eventual non-zero exit from send-pack, and propagates that in
its own non-zero exit code. So at least a careful script invoking "git
push" would notice the failure. But sending the misleading message on
stderr is certainly confusing for humans (not to mention the
machine-readable "push --porcelain" output, though again, any careful
script should be checking the exit code from push, too).
Nobody seems to have noticed because the server in this instance has to
be misbehaving: it has promised to support the ref-status capability
(otherwise the client will not set EXPECTING_REPORT at all), but didn't
send us any. If the connection were simply cut, then send-pack would
complain about getting EOF while trying to read the status. But if the
server actually sends a flush packet (i.e., saying "now you have all of
the ref statuses" without actually sending any), then the client ends up
in this confused situation.
The fix is simple: we should return an error message from "send-pack
--helper-status", just like we would for any other error per-ref error
condition (in the test I included, the server simply omits all ref
status responses, but a more insidious version of this would skip only
some of them).

Note that it was also declared a "const char *". We could switch that to
