"git tag" started listing a tag "foo" as "tags/foo" when a branch
named "foo" exists in the same repository; remove this unnecessary
disambiguation, which is a regression introduced in v2.7.0.

* jk/list-tag-2.7-regression:
  tag: do not show ambiguous tag names as "tags/foo"
  t6300: use test_atom for some un-modern tests

* ew/svn-1.9.0-auth:
  git-svn: fix auth parameter handling on SVN 1.9.0+

"git shortlog" used to accumulate various pieces of information
regardless of what was asked to be shown in the final output.  It
has been optimized by noticing what need not to be collected
(e.g. there is no need to collect the log messages when showing
only the number of changes).

* jk/shortlog:
  shortlog: don't warn on empty author
  shortlog: optimize out useless string list
  shortlog: optimize out useless "<none>" normalization
  shortlog: optimize "--summary" mode
  shortlog: replace hand-parsing of author with pretty-printer
  shortlog: use strbufs to read from stdin
  shortlog: match both "Author:" and "author" on stdin

The preliminary clean-up for jc/peace-with-crlf topic.

* jc/strbuf-getline:
  strbuf: give strbuf_getline() to the "most text friendly" variant
  checkout-index: there are only two possible line terminations
  update-index: there are only two possible line terminations
  check-ignore: there are only two possible line terminations
  check-attr: there are only two possible line terminations
  mktree: there are only two possible line terminations
  strbuf: introduce strbuf_getline_{lf,nul}()
  strbuf: make strbuf_getline_crlf() global
  strbuf: miniscule style fix

Beginning of the upstreaming process of Git for Windows effort.

* js/msys2:
  mingw: uglify (a, 0) definitions to shut up warnings
  mingw: squash another warning about a cast
  mingw: avoid warnings when casting HANDLEs to int
  mingw: avoid redefining S_* constants
  compat/winansi: support compiling with MSys2
  compat/mingw: support MSys2-based MinGW build
  nedmalloc: allow compiling with MSys2's compiler
  config.mak.uname: supporting 64-bit MSys2
  config.mak.uname: support MSys2

"interpret-trailers" has been taught to optionally update a file in
place, instead of always writing the result to the standard output.

* tk/interpret-trailers-in-place:
  interpret-trailers: add option for in-place editing
  trailer: allow to write to files other than stdout

The description for SANITY prerequisite the test suite uses has
been clarified both in the comment and in the implementation.

* jk/sanity:
  test-lib: clarify and tighten SANITY

A recent optimization to filter-branch in v2.7.0 introduced a
regression when --prune-empty filter is used, which has been
corrected.

* jk/filter-branch-no-index:
  filter-branch: resolve $commit^{tree} in no-index case
