 =head2 Formatting a Limited Range of Lines
 
-A command B<--line-range-tidy=n1:n2> is available to pass just a selected range
-of lines to perltidy.  This command is mainly of interest to interactive
-code editors.  When it is used, just the selected range of lines are passed
-through the perltidy tokenizer and formatter, so they need to contain a
-complete statement or balanced container.  Otherwise, a syntax error will occur
-and the code will not be tidied.  There are a couple of limitations
-on the use of this command: (1) it may not be applied to multiple files, and
-(2) it only applies to code tidying and not, for example, html formatting.
