These were originally removed by 0232852 (t5537: move
http tests out to t5539, 2014-02-13). However, they were
accidentally re-added in 1ddb4d7 (Merge branch
'nd/upload-pack-shallow', 2014-03-21).

This looks like an error in manual conflict resolution.
Here's what happened:

  1. v1.9.0 shipped with the http tests in t5537.

  2. We realized that this caused problems, and built
     0232852 on top to move the tests to their own file.
     This fix made it into v1.9.1.

  3. We later had another fix in nd/upload-pack-shallow that
     also touched t5537. It was built directly on v1.9.0.

When we merged nd/upload-pack-shallow to master, we got a
conflict; it was built on a version with the http tests, but
we had since removed them. The correct resolution was to
drop the http tests and keep the new ones, but instead we
kept everything.

reversing changes made to e42552135a2a396f37053a89f44952ea907870b2.

The author of the original topic says he broke the upcoming 2.0
release with something that relates to "synchronization crash
regression" while refusing to give further specifics, so this would
unfortunately be the safest option for the upcoming release.

* rh/prompt-pcmode-avoid-eval-on-refname:
  git-prompt.sh: don't assume the shell expands the value of PS1

Not all shells subject the prompt string to parameter expansion.  Test
whether the shell will expand the value of PS1, and use the result to
control whether raw ref names are included directly in PS1.

This fixes a regression introduced in commit 8976500 ("git-prompt.sh:
don't put unsanitized branch names in $PS1"):  zsh does not expand PS1
by default, but that commit assumed it did.  The bug resulted in
prompts containing the literal string '${__git_ps1_branch_name}'
instead of the actual branch name.

  request-pull: resurrect for-linus -> tags/for-linus DWIM

Older versions of Git before v1.7.10 did not DWIM

    $ git pull $URL for-linus

to the tag "tags/for-linus" and the users were required to say

    $ git pull $URL tags/for-linus

instead.  Because newer versions of Git works either way,
request-pull used to show tags/for-linus when asked

    $ git request-pull origin/master $URL for-linus

The recent updates broke this and in the output we see "for-linus"
without the "tags/" prefix.

As v1.7.10 is more than 2 years old, this should matter very little
in practice, but resurrecting it is very simple.
