The current output of this is:

  function foo() {
    if (1 < 2)
    something1
  else
    something2
  fi
    return
  }

instead of

  function foo() {
    if (1 < 2)
      something1
    else
      something2
    fi
      return
  }

This is because the list has this contents:

  "if (1 < 2)" "\n"
  "  something1" "\n"
  "else" "\n"
  "  something2" "\n"
  "fi"

So the indentation that you see inside the resulting "if" block is the
indentation that is internal to the `list' expression, ignoring the
context.  Here's a more exaggerated example:

  #lang scribble/text
  function foo() {
          newline
          @list{if (1 < 2)
                  something1
                else
                  something2
                fi
                }
          return
  }

prints:

  function foo() {
          newline
          if (1 < 2)
    something1
  else
    something2
  fi
          return
  }
