status: disable translation when --porcelain is used

"git status --branch --porcelain" displays the status of the branch
(ahead, behind, gone), and used gettext to translate the string.

Use hardcoded strings when --porcelain is used, but keep the gettext
translation for "git status --short" which is essentially the same, but
meant to be read by a human.

Documentation/gitk: document the location of the configulation file

User config file location complies with the XDG base directory
specification while supporting the traditional $HOME/.gitk as a
fallback.

fsck: use bitwise-or assignment operator to set flag

fsck_tree() has two different ways to set a flag variable, either by
using a if-statement that guards an assignment, or by using a
bitwise-or assignment operator.  Most are done with the former, and
only one variable is assigned with the latter.

Since all the conditions are short-and-sweet, we can afford to
uniformly use the latter style, which makes the resulting code
shorter and easier to read.

object.h: centralize object flag allocation

While the field "flags" is mainly used by the revision walker, it is
also used in many other places. Centralize the whole flag allocation to
one place for a better overview (and easier to move flags if we have
too).

Merge branch 'cn/fetch-prune-overlapping-destination' into jch

Protect refs in a hierarchy that can come from more than one remote
hierarcies from incorrect removal by "git fetch --prune".

Comments?

* cn/fetch-prune-overlapping-destination:
  fetch: handle overlaping refspecs on --prune
  fetch: add a failing test for prunning with overlapping refspecs

Merge branch 'ks/tree-diff-nway' into jch

Instead of running N pair-wise diff-trees when inspecting a
N-parent merge, find the set of paths that were touched by walking
N+1 trees in parallel.  These set of paths can then be turned into
N pair-wise diff-tree results to be processed through rename
detections and such.  And N=2 case nicely degenerates to the usual
2-way diff-tree, which is very nice.

* ks/tree-diff-nway:
  combine-diff: speed it up, by using multiparent diff tree-walker directly
  tree-diff: rework diff_tree() to generate diffs for multiparent cases as well

  tree-diff: don't assume compare_tree_entry() returns -1,0,1
  tree-diff: consolidate code for emitting diffs and recursion in one place
  tree-diff: show_tree() is not needed
  tree-diff: no need to pass match to skip_uninteresting()
  tree-diff: no need to manually verify that there is no mode change for a path
  combine-diff: move changed-paths scanning logic into its own function
  combine-diff: move show_log_first logic/action out of paths scanning
