We'll never see a NULL returned from git_prompt(); if it can't produce
any input for us (e.g., because the terminal got EOF) then it will just
die().
So there's no need for us to handle NULL here. And even if there was, it
doesn't make sense to continue; on a true terminal hangup we'd just loop
infinitely trying to get input that will never come.

Since commit 545dc345eb (progress: break too long progress bar lines,
2019-04-12) when splitting a too long progress line, sometimes it
looks as if a superfluous empty line were added between the title
line and the counters.
To make sure that the previously displayed progress line is completely
covered up when writing the new, shorter title line, we calculate how
many characters need to be overwritten with spaces. Alas, this
calculation doesn't account for the newline character at the end of
the new title line, and resulted in printing one more space than
strictly necessary. This extra space character doesn't matter, if the
length of the previous progress line was shorter than the width of the
terminal. However, if the previous line matched the terminal width,
then this extra space made the new line longer, effectively adding
that empty line after the title line.
Fix this off-by-one to avoid that spurious empty line.

The descriptions of the GIT_TRACE2* environment variables link to the
technical docs for further details on the supported values. However,
a link like this only really works if the docs are viewed in a browser
and the full documentation is available. OTOH, in 'man git' there are
no links to conveniently click on, and distro-shipped git packages
tend to include only the man pages, while the technical docs and the
docs in html format are in a separate 'git-doc' package.
So let's describe the supported values to make the manpage more
self-contained, but still keep the references to the technical docs
because the details of the SID, and the JSON and perf output formats
are definitely beyond the scope of 'man git'.

For an environment variable that is supposed to be set by users, the
GIT_TR2* env vars are just too unclear, inconsistent, and ugly.
Most of the established GIT_* environment variables don't use
abbreviations, and in case of the few that do (GIT_DIR,
GIT_COMMON_DIR, GIT_DIFF_OPTS) it's quite obvious what the
abbreviations (DIR and OPTS) stand for. But what does TR stand for?
Track, traditional, trailer, transaction, transfer, transformation,
transition, translation, transplant, transport, traversal, tree,
trigger, truncate, trust, or ...?!
The trace2 facility, as the '2' suffix in its name suggests, is
supposed to eventually supercede Git's original trace facility. It's
reasonable to expect that the corresponding environment variables
follow suit, and after the original GIT_TRACE variables they are
called GIT_TRACE2; there is no such thing is 'GIT_TR'.
All trace2-specific config variables are, very sensibly, in the
'trace2' section, not in 'tr2'.
OTOH, we don't gain anything at all by omitting the last three
characters of "trace" from the names of these environment variables.
So let's rename all GIT_TR2* environment variables to GIT_TRACE2*,
before they make their way into a stable release.

Since 7171d8c15f (upload-pack: send symbolic ref information as
capability, 2013-09-17), we've sent cloning and fetching clients special
information about which branch HEAD is pointing to, so that they don't
have to guess based on matching up commit ids.
However, this feature has never worked properly with the GIT_NAMESPACE
feature. Because upload-pack uses head_ref_namespaced(find_symref), we
do find and report on refs/namespaces/foo/HEAD instead of the actual
HEAD of the repo. This makes sense, since the branch pointed to by the
top-level HEAD may not be advertised at all. But we do two things wrong:
1. We report the full name refs/namespaces/foo/HEAD, instead of just
HEAD. Meaning no client is going to bother doing anything with that
symref, since we're not otherwise advertising it.
2. We report the symref destination using its full name (e.g.,
refs/namespaces/foo/refs/heads/master). That's similarly useless to
the client, who only saw "refs/heads/master" in the advertisement.
We should be stripping the namespace prefix off of both places (which
this patch fixes).
Likely nobody noticed because we tend to do the right thing anyway. Bug
(1) means that we said nothing about HEAD (just refs/namespace/foo/HEAD).
And so the client half of the code, from a45b5f0552 (connect: annotate
refs with their symref information in get_remote_head(), 2013-09-17),
does not annotate HEAD, and we use the fallback in guess_remote_head(),
matching refs by object id. Which is usually right. It only falls down
in ambiguous cases, like the one laid out in the included test.
This also means that we don't have to worry about breaking anybody who
was putting pre-stripped names into their namespace symrefs when we fix
bug (2). Because of bug (1), nobody would have been using the symref we
advertised in the first place (not to mention that those symrefs would
have appeared broken for any non-namespaced access).
Note that we have separate fixes here for the v0 and v2 protocols. The
symref advertisement moved in v2 to be a part of the ls-refs command.
This actually gets part (1) right, since the symref annotation
piggy-backs on the existing ref advertisement, which is properly
stripped. But it still needs a fix for part (2). The included tests
cover both protocols.

There appears to be a bug in the toolchain generating manpages from
lettered lists. When a list is enumerated with letters, the resulting
nroff shows numbers instead. Mostly this is harmless, but in the case of
gitsubmodules, the paragraph following the list refers back to each
bullet by letter. As a result, reading this documentation via `man
gitsubmodules` is hard to parse - readers must infer that a bug exists
and a refers to 1, b refers to 2, and c refers to 3 in the list above.
The problem specifically was introduced in ad47194; previously rather
than generating numerated lists the bulleted area was entirely
monospaced in HTML and shown in plaintext in nroff.
The bug seems to exist in docbook-xml - I've reported it on May 1 via
the docbook-apps mail list - but for now it may make more sense to just
work around the issue.

When a remote helper exposes the "import" capability, stdout of the
helper is sent to stdin of a new fast-import process. This is done by
setting the corresponding child_process's in field to the value of the
out field of the helper child_process.
The child_process API is defined to close the file descriptors it's
given when calling start_command. This means when start_command is
called for the fast-import process, its input fd (the output fd of the
helper), is closed.
But when the transport helper is later destroyed, in disconnect_helper,
its input and output are closed, which means close() is called with
an invalid fd (since it was already closed as per above). Or worse, with
a valid fd owned by something else (since fd numbers can be reused).

The function's definition has a paramter of type "int" qualified as
"const". The fact that the incoming parameter is used as read-only
in the fuction is an implementation detail that the callers should
not have to be told in the prototype declaring it (and "const" there
has no effect, as C passes parameters by value).
The prototype defined for the function in pkt-line.h lacked the
matching "const" for this reason, but apparently some compilers
(e.g. MS Visual C 2017) complain about the parameter type mismatch.
Let's squelch it by removing the "const" that is pointless in the
definition of a small and trivial function like this, which would
not help optimizing compilers nor reading humans that much.

The JGIT prereq uses `type jgit` to determine whether jgit is present.
While this is usually sufficient, it won't help if the jgit found is
badly broken. This wastes time running tests which fail due to no fault
of our own.
Use `jgit --version` instead, to guard against cases where jgit is
present on the system, but will fail to run, e.g. because of some JRE
issue, or missing Java dependencies. Checking that it gets far enough
to process the '--version' argument isn't perfect, but seems to be good
enough in practice. It's also consistent with how we detect some other
dependencies, see e.g. the CURL and UNZIP prerequisites.
