Some HTTP servers try to use gzip compression on the /info/refs
request to save transfer bandwidth. Repositories with many tags
may find the /info/refs request can be gzipped to be 50% of the
original size due to the few but often repeated bytes used (hex
SHA-1 and commonly digits in tag names).

For most HTTP requests enable "Accept-Encoding: gzip" ensuring
the /info/refs payload can use this encoding format.

Only request gzip encoding from servers. Although deflate is
supported by libcurl, most servers have standardized on gzip
encoding for compression as that is what most browsers support.
Asking for deflate increases request sizes by a few bytes, but is
unlikely to ever be used by a server.

Disable the Accept-Encoding header on probe RPCs as response bodies
are supposed to be exactly 4 bytes long, "0000". The HTTP headers
requesting and indicating compression use more space than the data
transferred in the body.

As reported by Jeroen Meijer[1]; the current code doesn't deal properly
with items (tags, branches, etc.) that have ${} in them because they get
expaned by bash while using compgen.

A simple solution is to quote the items so they get expanded properly
(\$\{\}).

In order to achieve that I took bash-completion's quote() function,
which is rather simple, and renamed it to __git_quote() as per Jeff
King's suggestion.

Solves the original problem for me.

The attribute system may be asked for a path that itself or its
leading directories no longer exists in the working tree, and it is
fine if we cannot open .gitattribute file in such a case.  Failure
to open per-directory .gitattributes with error status other than
ENOENT and ENOTDIR should be diagnosed.

The note that explains that changes introduced by removed commits are
preserved should be placed directly after the paragraph that describes
such commits removal.  Otherwise the reference to "the commits" appears
out of context.

Also the big example that follows "Consider this history" is about
rewriting part of the history DAG.  Move the paragraph that
describes the operation close to it.

Often we consult an in-tree .gitattributes file that exists per
directory.  Majority of directories do not usually have such a file,
and it is perfectly fine if we cannot open it because there is no
such file, but we do want to know when there is an I/O or permission
error.  Earlier, we made the codepath warn when we fail to open it
for reasons other than ENOENT for that reason.

We however sometimes have to attempt to open the .gitattributes file
from a directory that does not exist in the commit that is currently
checked out.  "git pack-objects" wants to know if a path is marked
with "-delta" attributes, and "git archive" wants to know about
export-ignore and export-subst attributes.  Both commands may and do
need to ask the attributes system about paths in an arbitrary
commit.  "git diff", after removing an entire directory, may want to
know textconv on paths that used to be in that directory.

Make sure we also ignore a failure to open per-directory attributes
file due to ENOTDIR.

"git apply -p0" did not parse pathnames on "diff --git" line
correctly.  This caused patches that had pathnames in no other
places to be mistakenly rejected (most notably, binary patch that
does not rename nor change mode).  Textual patches, renames or mode
changes have preimage and postimage pathnames in different places in
a form that can be parsed unambiguously and did not suffer from this
problem.

* jc/apply-binary-p0:
  apply: compute patch->def_name correctly under -p0

"git log .." errored out saying it is both rev range and a path when
