gno fmt adds an extra line at the end of the file

Since it is asserted in the tests (See screenshot of gnovm/pkg/gnofmt/processes_test.go), it looks like this extra line is added on purpose, but I wonder what's the reason of having this difference compared to go fmt.

Thanks for reporting this !

So, actually go fmt makes sure that a newline exists at the end of the file. The picture of the test you sent asserts this (under the hood gnofmt/gnoimports is used to format the file).

But you are right, there is another newline being printed out ($ means newline, % means EOF):

This is due to a Println instead of a Printf inside the cmd itself while writing the file to disk.

I will fix this asap.

After double-checking, this behavior only exists when printing on stdout (without the -w flag). It was intentional to have a space between files for distinction (gno fmt file_1.gno file_2.gno ... ), but upon second thought, it might be more coherent and intuitive to have the same behavior as go fmt and print out files without consideration of newlines between printed files.

Great, thanks for the fix!
