real real patch.
Sorry >_< my latest "real patch" was the very same file as the wrong patch...
> IBM420 charset detection's isLamAlef is allocation-happy

> Issue Type: Bug
> Components: parser
> Affects Versions: 0.8
> Reporter: Radek
> Assignee: Ken Krugler
> Priority: Minor
> Attachments: isLamAlef.diff

>
> Two IBM420 charset detectors (rtl and ltr) run isLamAlef() for each byte of
> detection buffer.
> The code is allocating and filling a bytes array every time it runs, which
> makes it responsible for approximately 70% of all object allocations in my
> current test case (many text files).
> Since array is identical every time, and the entire thing can be achieved
> without any array, this is wasteful.
