Merge branch 'jc/fetch-raw-sha1' into jch

Allows requests to fetch objects at any tip of refs (including
hidden ones).  It seems that there may be use cases even outside
Gerrit (e.g. $gmane/215701).

Will cook in 'next'.

Merge branch 'jc/remove-treesame-parent-in-simplify-merges' into jch

The --simplify-merges logic did not cull irrelevant parents from a
merge that is otherwise not interesting with respect to the paths
we are following.

This touches a fairly core part of the revision traversal
infrastructure; even though I think this change is correct, please
report immediately if you find any unintended side effect.

Will cook in 'next'.

* jc/remove-treesame-parent-in-simplify-merges:
  simplify-merges: drop merge from irrelevant side branch

Merge branch 'jc/remove-export-from-config-mak-in' into jch

config.mak.in template had an "export" line to cause a few
common makefile variables to be exported; if they need to be
expoted for autoconf/configure users, they should also be exported
for people who write config.mak the same way.  Move the "export" to
the main Makefile.  Also, stop exporting mandir that used to be
exported (only) when config.mak.autogen was used.  It would have
broken installation of manpages (but not other documentation
formats).

Will cook in 'next'.

* jc/remove-export-from-config-mak-in:
  Fix `make install` when configured with autoconf
  Makefile: do not export mandir/htmldir/infodir
  config.mak.in: remove unused definitions

Conflicts:
	config.mak.in
Merge branch 'nd/read-directory-recursive-optim' into jch

"git status" has been optimized by taking advantage of the fact

checked against the .gitignore mechanism under some conditions.

Will cook in 'next'.

* nd/read-directory-recursive-optim:
  read_directory: avoid invoking exclude machinery on tracked files
Merge branch 'jc/push-2.0-default-to-simple' into jch
