The following snippet

    CURL* hCurlHandle = curl_easy_init();

    curl_easy_perform(hCurlHandle);
    curl_easy_cleanup(hCurlHandle);
    return 0;
}
```

Fish defines a vendor completions directory for completions that are not
installed as part of the fish project itself, and the vendor completions
are preferred if they exist. This prevents trying to overwrite the
builtin curl.fish completion (or creating file conflicts in distro
packaging).

Prefer the pkg-config defined location exported by fish, if it can be
found, and fall back to the correct directory defined by most systems.

- Fix clang string-plus-int warning.

Clang 8 warns about adding a string to an int does not append to the
string. Indeed it doesn't, but that was not the intention either. Use
array indexing as suggested to silence the warning. There should be no
functional changes.

(In other words clang warns about "foo"+2 but not &"foo"[2] so use the
latter.)

string [-Wstring-plus-int]

All Windows APIs have been natively UTF-16 since Windows 2000 and the
non-Unicode variants are just wrappers around them. Only Windows 9x
doesn't understand Unicode without the UnicoWS DLL. As later Visual
Studio versions cannot target Windows 9x anyway, using the ANSI API
doesn't really have any benefit there.

This avoids issues like KNOWN_BUGS 6.5.

Already done in commit d5cfefd0 for the
library project, but I forgot the tool project template. Now also
removed for that.

Try to run as many test cases as possible on each OS version.
12.0 passes 13 more tests than the older versions, so we might as well

- Improve console detection.

Prior to this change WriteConsole could be called to write to a handle
that may not be a console, which would cause an error. This issue is
limited to character devices that are not also consoles such as the null
device NUL.
