72b6eeb81b cmake: do find Git for Windows' shell interpreter
By default, Git for Windows does not install its `sh.exe` into the
`PATH`. However, our current `CMakeLists.txt` expects to find a shell
interpreter in the `PATH`.

So let's fall back to looking in the default location where Git for
Windows _does_ install a relatively convenient `sh.exe`:
`C:\Program Files\Git\bin\sh.exe`

3eccc7b99d cmake: ignore files generated by CMake as run in Visual Studio
As of recent Visual Studio versions, CMake support is built-in:
https://docs.microsoft.com/en-us/cpp/build/cmake-projects-in-visual-studio?view=vs-2019

All that needs to be done is to open the worktree as a folder, and
Visual Studio will find the `CMakeLists.txt` file and automatically
generate the project files.

Let's ignore the entirety of those generated files.

67bb65de5d packfile: actually set approximate_object_count_valid
The approximate_object_count() function tries to compute the count only
once per process. But ever since it was introduced in 8e3f52d778
(find_unique_abbrev: move logic out of get_short_sha1(), 2016-10-03), we
failed to actually set the "valid" flag, meaning we'd compute it fresh
on every call.

This turns out not to be _too_ bad, because we're only iterating through
the packed_git list, and not making any system calls. But since it may
get called for every abbreviated hash we output, even this can add up if
you have many packs.

Here are before-and-after timings for a new perf test which just asks
rev-list to abbreviate each commit hash (the test repo is linux.git,
with commit-graphs):

  Test                            origin              HEAD
  ----------------------------------------------------------------------------
  5303.3: rev-list (1)            28.91(28.46+0.44)   29.03(28.65+0.38) +0.4%
  5303.4: abbrev-commit (1)       1.18(1.06+0.11)     1.17(1.02+0.14) -0.8%
  5303.7: rev-list (50)           28.95(28.56+0.38)   29.50(29.17+0.32) +1.9%
  5303.8: abbrev-commit (50)      3.67(3.56+0.10)     3.57(3.42+0.15) -2.7%
  5303.11: rev-list (1000)        30.34(29.89+0.43)   30.82(30.35+0.46) +1.6%
  5303.12: abbrev-commit (1000)   86.82(86.52+0.29)   77.82(77.59+0.22) -10.4%
  5303.15: load 10,000 packs      0.08(0.02+0.05)     0.08(0.02+0.06) +0.0%

It doesn't help at all when we have 1 pack (5303.4), but we get a 10%
speedup when there are 1000 packs (5303.12). That's a modest speedup for
a case that's already slow and we'd hope to avoid in general (note how
slow it is even after, because we have to look in each of those packs
for abbreviations). But it's a one-line change that clearly matches the
original intent, so it seems worth doing.

The included perf test may also be useful for keeping an eye on any
regressions in the overall abbreviation code.

Add tests covering the behavior of passing multiple contains/no-contains
filters to git branch, e.g.:

$ git branch --contains feature_a --contains feature_b
$ git branch --no-contains feature_a --no-contains feature_b

When passed more than one contains (or no-contains) filter, the tips of
the branches returned must be reachable from any of the contains commits
and from none of the the no-contains commits.

This logic is useful to describe prior to enabling multiple
merged/no-merged filters, so that future tests will demonstrate
consistent behavior between merged/no-merged and contains/no-contains
filters.

e2773aa45f quote_path: code clarification
The implementation we moved from wt-status to enclose a pathname
that has a SP in it inside a dq-pair is a bit convoluted.  It lets
quote_c_style_counted() do its escaping and then

 (1) if the input string got escaped, which is checked by seeing if
     the result begins with a double-quote, declare that we are
     done.  If there wasn't any SP in the input, that is OK, and if
     there was, the result is quoted already so it is OK, too.

 (2) if the input string did not get escaped, and the result has SP
     in it, enclose the whole thing in a dq-pair ourselves.

Instead we can scan the path upfront to see if the input has SP in
it.  If so, we tell quote_c_style_counted() not to enclose its
output in a dq-pair, and we add a dq-pair ourselves.  Whether the
input had bytes that quote_c_style_counted() uses backslash quoting,
this would give us a desired quoted string.  If the input does not
have SP in it, we just let quote_c_style_counted() do its thing as
usual, which would enclose the result in a dq-pair only when needed.
