Isn't there some option you can pass for max_line_length? Google for "PerlTidy max line length"?

Showing " -l=n, --maximum-line-length=n" The default maximum line length is n=80 characters

So unless you specify it, 80 is what you get.

What exactly is the style you are trying to achieve?

Maybe you want -l=0?

A basic glance at the perltidy docs says:

FORMATTING OPTIONS

Basic Options

-l=n, --maximum-line-length=n

    The default maximum line length is n=80 characters. Perltidy will 
+try to find line break points to keep lines below this length. Howeve
+r, long quotes and side comments may cause lines to exceed this lengt
+h. Setting -l=0 is equivalent to setting -l=(a large number).
