"git cmd <name>", when <name> happens to be a 40-hex string,
directly uses the 40-hex string as an object name, even if a ref
"refs/<some hierarchy>/<name>" exists.  This disambiguation order
is unlikely to change, but we should warn about the ambiguity just
like we warn when more than one refs/ hierachies share the same
name.

A git daemon that starts as "root" and then drops privilege often
leaves $HOME set to that of the root user, which is unreadable by
the daemon process, which was diagnosed as a configuration error.

Make per-user configuration files that are inaccessible due to
EACCES as though these files do not exist to avoid this issue, as
the tightening which was originally meant as an additional security
has annoyed enough sysadmins.

  config: allow inaccessible configuration under $HOME

The bug is manifest when running gitweb in a persistent process (e.g.
FastCGI, PSGI), and it's easy to reproduce.  If a gitweb request
includes the searchtext parameter (i.e. s), subsequent requests using
the project_list action--which is the default action--and without
a searchtext parameter will be filtered by the searchtext value of the
first request.  This is because the value of the $search_regexp global
(the value of which is based on the searchtext parameter) is currently
being persisted between requests.

Instead, clear $search_regexp before dispatching each request.

When explaining the "--tags" option as an equivalent to giving an
explicit "refs/tags/*:refs/tags/*" refspec, the two asterisks were
misinterpreted by AsciiDoc as a request to typeset the string
segment between them in bold.

We could fix it in two ways.  We can replace them with {asterisk}s
while keeping the string as body text, or we can mark it as a
literal string with backquotes around it.

Let's do the latter, as it is teaching the user an "exactly as
typed" alternative.

Collected msysgit build patches for upstream

This set of patches collects a number of build fixes that have been
used on the msysgit port for a while and merging upstream should
simplify future maintenance.

* tag 'post183-for-junio' of http://github.com/msysgit/git:
  Set the default help format to html for msys builds.
  Ensure the resource file is rebuilt when the version changes.
  Windows resource: handle dashes in the Git version gracefully
  Provide a Windows version resource for the git executables.
  msysgit: Add the --large-address-aware linker directive to the makefile.
  Define NO_GETTEXT for Git for Windows
  Makefile: Do not use OLD_ICONV on MINGW anymore

"git push $there HEAD:branch" did not resolve HEAD early enough, so
it was easy to flip it around while push is still going on and push
out a branch that the user did not originally intended when the
command was started.

  push: make push.default = current use resolved HEAD
  push: fail early with detached HEAD and current
  push: factor out the detached HEAD error message

"difftool --dir-diff" did not copy back changes made by the
