* [tests] Test fzf's placeholders and escaping on practical commands
This tests some reasonable commands in fzf's templates (for commands,
previews, rebinds etc.), how are those commands escaped (backslashes,
double quotes), and documents if the output is executable in cmd.exe.
Both on Unix and Windows.
* [tests] Add testing of placeholder parsing and matching
Adds tests and bit of docs for the curly brackets placeholders in fzf's
template strings. Also tests the "placeholder" regex.
* [tests] Add more test cases of replacing placeholders focused on flags
Replacing placeholders in templates is already tested, this adds tests
that focus more on the parameters of placeholders - e.g. flags, token
ranges.
There is at least one test for each flag, not all combinations are
tested though.
* [refactoring] Split OS-specific function quoteEntry() to corresponding source file
This is minor refactoring, and also the function's test was made
crossplatform.
* [refactoring] Simplify replacePlaceholder function
Should be equivalent to the original, but has simpler structure.
Most of the "expected" strings in terminal.go test were changed to
"text/template" values. Quotes in those string were parametrized in
the templates. Two functions handling templates were added
for convenience.
Templates has the advantage of:
- parametrize repetitive strings inside "expected" values
- inner and outer quotes were parametrized in templates
- long and confusing test values are more readable
- templates can be localized for other operating systems

Close#1018
Run the command as is in cmd.exe with no parsing and escaping.
Explicity set cmd.SysProcAttr so execCommand does not escape the command.
Technically, the command should be escaped with ^ for special characters,
including ". This allows cmd.exe commands to be chained together.
See https://github.com/neovim/neovim/pull/7343#issuecomment-333350201
This commit also updates quoteEntry to use strings.Replace instead of
strconv.Quote which escapes more than \ and ".
