Doubled output in `spatialite` CLI (MSYS2)

[Konstantin Podsvirov]

For `spatialite` CLI from MSYS2 I get doubled output:

```

spatialite> SELECT id, AsText(location) AS location FROM towns;

SELECT id, AsText(location) AS location FROM towns;

id          location

----------  ------------

1           1           POINT(33 44)

POINT(33 44)

```

But with `sqlite3` with `mod_spatialite` all as aspected:

```

sqlite> SELECT id, AsText(location) AS location FROM towns;

SELECT id, AsText(location) AS location FROM towns;

id  location

--  ------------

1   POINT(33 44)

```

Hi Konstantin,

I'm unable to confirm your problem, however I can confirm that

MSYS2 surely has many troubles in correctly supporting the

CLI tool.

this is what I can see on my own mingw32.exe / mingw64.exe shells:

a. spatialite_cli.exe is unable to show any output at all on   

   the console's screen

b. and the same is for sqlite3.exe from the canonical "pacman"

   distribution in -/mingw64/bin

   

both the stdout and stderr files work nicely when redirected 

as e.g. in

 

spatialite >out1 2> out2

they correctly work on the MS cmd.exe command shell, and the

same code works nicely on Linux.

my personal conclusion is that MSYS2 has some obscure 

idiosynchrasy forbidding to correctly hanlde stdout

and stderr in the same way supported by native cmd.exe
