possible innstat.in fix for inn-2.4.2-test

[Chris Caputo]

Hi.  On inn-2.4.2-test innstat is reporting the following when used with
FSF's "tail (coreutils) 5.2.1":

---
Batch file sizes:
tail: cannot open `+2' for reading: No such file or directory
---

I've attached a possible fix below, but unfortunately I don't know if it 
will fare well with older versions of tail.

Chris
