Added strio.ChompLines()
Added justification for not checking Wait() result
Fixed formatting bug in displaying changes

Using echo to send the contents of the variable $FMT to less caused
escaped newlines in the source code to be interpreted and caused
incorrectly formatted output of newline literals. Consider a code change
such as the following:

    - fmt.Printf("%s\n",  var)
    + fmt.Printf("%s\n", var)

This change would be rendered by the previous script as:

    - fmt.Printf("%s
    ",  var)
    + fmt.Printf("%s
    ", var)
Removed fmtsrc.sh

In future, style rules will be enforced by gofmt and will not be optional.
Outputting of applied changes (gofmt -d -s $(SRCDIR)) will be kept for the
moment, as it may be useful to be able to see changes gofmt is enforcing. This
may be changed in future.
