Fetching from a shallow-cloned repository used to be forbidden,
primarily because the codepaths involved were not carefully vetted
and we did not bother supporting such usage. This attempts to allow
object transfer out of a shallow-cloned repository in a controlled
way (i.e. the receiver become a shallow repository with truncated
history).

Finishing touches so that an expected error message will not leak to
the UI.
* jk/pull-rebase-using-fork-point:
pull: suppress error when no remoteref is found
Commit 48059e4 (pull: use merge-base --fork-point when appropriate,
2013-12-08) incorrectly assumes that get_remote_merge_branch will either
yield a non-empty string or return an error, but there are circumstances
where it will yield an empty string.
The previous code then invoked git-rev-list with no arguments, which
results in an error suppressed by redirecting stderr to /dev/null. Now
we invoke git-merge-base with an empty branch name, which also results
in an error. Suppress this in the same way.

With a submodule that was initialized in an old fashioned way

When parsing a 40-hex string into the object name, the string is
checked to see if it can be interpreted as a ref so that a warning
can be given for ambiguity. The code kicked in even when the
core.warnambiguousrefs is set to false to squelch this warning, in
which case the cycles spent to look at the ref namespace were an
expensive no-op, as the result was discarded without being used.

The "--[no-]informative-errors" options to "git daemon" were parsed

Commit 43eb920 switched one of the sub-repository in this
test to matching to prepare for a world where the default
becomes "simple". However, the main repository needs a
similar change.
We did not notice any test failure when merged with b2ed944
(push: switch default from "matching" to "simple", 2013-01-04)
because t5531.6 is trying to provoke a failure of "git push"
due to a submodule check. When combined with b2ed944 the
push still fails, but for the wrong reason (because our
upstream setup does not exist, not because of the submodule).

There is no guarantee that strbuf_read_file must error out for
directories. On some operating systems (e.g., Debian GNU/kFreeBSD
wheezy), reading a directory gives its raw content:
$ head -c5 < / | cat -A
^AM-|^_^@^L$
As a result, 'git diff -O/' succeeds instead of erroring out on
these systems, causing t4056.5 "orderfile is a directory" to fail.
On some weird OS it might even make sense to pass a directory to the
-O option and this is not a common user mistake that needs catching.
Remove the test.

The previous commit c57f628 (mv: let 'git mv file no-such-dir/' error out)
relies on that rename("file", "no-such-dir/") fails if the directory does not
exist (note the trailing slash). This does not work as expected on Windows:
This rename() call does not fail, but renames "file" to "no-such-dir" (not to
"no-such-dir/file"). Insert an explicit check for this case to force an error.
This changes the error message from
$ git mv file no-such-dir/
fatal: renaming 'file' failed: Not a directory
to
$ git mv file no-such-dir/
fatal: destination directory does not exist, source=file, destination=no-such-dir/

"git help $cmd" unnecessarily enumerated potential command names
from the filesystem, even when $cmd is known to be a built-in.
Ideas for further optimization, primarily by killing the use of
is_in_cmdlist(), were suggested in the discussion, but they can

When we figure out how many file descriptors to allocate for
keeping packfiles open, a system with non-working getrlimit() could

fall back to a reasonable low value rather than dying.
