It could be misleading to keep a signature in a
replacement commit, so let's remove it.

Note that there should probably be a way to sign
the replacement commit created when using --graft,
but this can be dealt with in another commit or
patch series.

This patch adds into contrib/ an example script to convert
grafts from an existing grafts file into replace refs using
the new --graft option of "git replace".

While at it let's mention this new script in the
"git replace" documentation for the --graft option.

The usage string for this option is:

git replace [-f] --graft <commit> [<parent>...]

First we create a new commit that is the same as <commit>
except that its parents are [<parents>...]

Then we create a replace ref that replace <commit> with
the commit we just created.

With this new option, it should be straightforward to
convert grafts to replace refs.

In the same way as there is for_each_ref() to iterate on refs,
for_each_mergetag() allows the caller to iterate on the mergetags of
a given commit.  Use it to rewrite show_mergetag() used in "git log".

We create a directory that cannot be removed, confirm that
it cannot be removed, and then fix it like:

  chmod 0 foo &&
  test_must_fail git clean -d -f &&
  chmod 755 foo

If the middle step fails but leaves the directory (e.g., the
bug is that clean does not notice the failure), this
pollutes the test repo with an unremovable directory. Not
only does this cause further tests to fail, but it means
that "rm -rf" fails on the whole trash directory, and the
user has to intervene manually to even re-run the test script.

We can bump the "chmod 755" recovery to a test_when_finished
block to be sure that it always runs.

  gitk: Add visiblerefs option, which lists always-shown branches
  gitk: Catch mkdtemp errors
  gitk: Use mktemp -d to avoid predictable temporary directories
  gitk: Honor TMPDIR when viewing external diffs

When many branches contain a commit, the branches used to be shown in
the form "A, B and many more", where A, B can be master of current
HEAD. But there are more which might be interesting to always know about.
For example, "origin/master".

The new option, visiblerefs, is stored in ~/.gitk. It contains a list
of references which are always shown before "and many more" if they
contain the commit. By default it is `{"master"}', which is compatible
with previous behavior.

105b5d3f ("gitk: Use mktemp -d to avoid predictable temporary
directories") introduced a dependency on mkdtemp, which is not
available on Windows.

Use the original temporary directory behavior when mkdtemp fails.
This makes the code use mkdtemp when available and gracefully
fallback to the existing behavior when it is not available.

"git status" (and "git commit") behaved as if changes in a modified
submodule are not there if submodule.*.ignore configuration is set,
which was misleading.  The configuration is only to unclutter diff
output during the course of development, and should not to hide
changes in the "status" output to cause the users forget to commit
them.
