Gofmt formats Go programs.
It uses tabs for indentation and blanks for alignment.
Alignment assumes that an editor is using a fixed-width font.

Without an explicit path, it processes the standard input.  Given a file,
it operates on that file; given a directory, it operates on all .go files in

a cost of an additional 0.1% text and binary size.  This is currently only implemented
on 386 and amd64 because it has not shown an improvement on other platforms.
