When the user does the lazy "git push" with no parameters with
push.default set to either "upstream", "simple" or "current",
we internally generated a refspec that has the current branch name
on the source side and used it to push.

However, the branch name (say "test") may be an ambiguous refname in
the context of the source repository---there may be a tag with the
same name, for example.  This would trigger an unnecessary error
without any fault on the end-user's side.

Be explicit and give a full refname as the source side to avoid the
ambiguity.  The destination side when pushing with the "current"
sent only the name of the branch and forcing the receiving end to
guess, which is the same issue.  Be explicit there as well.

The "are we talking with TTY, doing an interactive session?"
detection has been updated to work better for "Git for Windows".

dir-diff mode.

A couple of bugs around core.autocrlf have been fixed.

  convert.c: ident + core.autocrlf didn't work

Many commands normalize command line arguments from NFD to NFC
variant of UTF-8 on OSX, but commands in the "diff" family did
not, causing "git diff $path" to complain that no such path is
known to Git.  They have been taught to do the normalization.

  diff: run arguments through precompose_argv

Correct faulty recommendation to use "git submodule deinit ." when
de-initialising all submodules, which would result in a strange
error message in a pathological corner case.

* sb/submodule-deinit-all:
  submodule deinit: require '--all' instead of '.' for all submodules

"http.cookieFile" configuration variable clearly wants a pathname,
but we forgot to treat it as such by e.g. applying tilde expansion.
