Merge branch 'rt/rebase-p-no-merge-summary'

"git rebase -p" internally used the merge machinery, but when

Merge branch 'es/rebase-i-no-abbrev'

The commit object names in the insn sheet that was prepared at the
beginning of "rebase -i" session can become ambiguous as the
rebasing progresses and the repository gains more commits. Make
sure the internal record is kept with full 40-hex object names.

Merge branch 'jc/ls-files-killed-optim'

"git ls-files -k" needs to crawl only the part of the working tree
that may overlap the paths in the index to find killed files, but
shared code with the logic to find all the untracked files, which
made it unnecessarily inefficient.

http-backend: provide Allow header for 405

The HTTP 1.1 standard requires an Allow header for 405 Method Not Allowed:

  The response MUST include an Allow header containing a list of valid methods
  for the requested resource.

So provide such a header when we return a 405 to the user agent.

Allow git-filter-branch to process large repositories with lots of branches.

A recommended way to move trees between repositories is to use
git-filter-branch to revise the history for a single tree:

However, this can lead to "argument list too long" errors when the
original repository has many retained branches (>6k)

    /usr/local/git/libexec/git-core/git-filter-branch: line 270:
    /usr/local/git/libexec/git-core/git: Argument list too long
    Could not get the commits

Saving the output from rev-parse and feeding it into rev-list from
its standard input avoids this problem, since the rev-parse output
is not processed as a command line argument.

commit: factor status configuration is a helper function

cmd_commit and cmd_status use very similar code to initialize the
wt_status structure. Factor this code into a function to ensure future
changes will keep both versions consistent.

wt-status: turn advice_status_hints into a field of wt_status

No behavior change in this patch, but this makes the display of status
hints more flexible as they can be enabled or disabled for individual
calls to commit.c:run_status().

commit: disable status hints when writing to COMMIT_EDITMSG

This turns the template COMMIT_EDITMSG from e.g

  # [...]
  # Changes to be committed:
  #   (use "git reset HEAD <file>..." to unstage)
  #
  #	modified:   builtin/commit.c
  #
  # Untracked files:
  #   (use "git add <file>..." to include in what will be committed)
  #
  #	t/foo
  #

to

  # [...]
  # Changes to be committed:
  #	modified:   builtin/commit.c
  #
  # Untracked files:
  #	t/foo
  #

Most status hints were written to be accurate when running "git status"
before running a commit. Many of them are not applicable when the commit
has already been started, and should not be shown in COMMIT_EDITMSG. The
most obvious are hints advising to run "git commit",
"git rebase/am/cherry-pick --continue", which do not make sense when the
command has already been run.

Other messages become slightly inaccurate (e.g. hint to use "git add" to
add untracked files), as the suggested commands are not immediately
applicable during the editing of COMMIT_EDITMSG, but would be applicable
if the commit is aborted. These messages are both potentially helpful and
slightly misleading. This patch chose to remove them too, to avoid
introducing too much complexity in the status code.

mailmap: work around implementations with pure inline strcasecmp

On some systems (e.g. MinGW 4.0), string.h has only inline
definition of strcasecmp and no non-inline implementation is
supplied anywhere, which is, eh, "unusual".  We cannot take an
address of such a function to store it in namemap.cmp.

Work it around by introducing our own level of indirection.

Add new @ shortcut for HEAD

Typing 'HEAD' is tedious, especially when we can use '@' instead.

The reason for choosing '@' is that it follows naturally from the
ref@op syntax (e.g. HEAD@{u}), except we have no ref, and no
operation, and when we don't have those, it makes sens to assume
'HEAD'.

So now we can use 'git show @~1', and all that goody goodness.

Until now '@' was a valid name, but it conflicts with this idea, so
let's make it invalid. Probably very few people, if any, used this name.
