extraneous newline in iostat report for long device names

iostat patch to remove extraneous newline for long device names
Description of problem:
iostat prints an extra unwanted newline for device names that exceed 13 chars
Version-Release number of selected component (if applicable):
all RHEL4 and RHEL5 versions of the sysstat package. This is
fixed upstream, simple patch attached.
How reproducible: always, just need long device names
Steps to Reproduce:
1. set up a long device name, e.g. a lengthy dm-multipath alias
2. run iostat
Actual results: extraneous newline after the device name
Expected results: no extraneous newline
upstream has removed this newline since sysstat-7.0.3,
There shouldn't be any issue affecting existing scripts that expect
to parse this newline (they should be tolerant of it not being present).
Bugfix was successfully verified on sysstat-7.0.2-8.el5 package on all supported architectures.
No new line is printed after device with long name.

When a device name was longer than 13 characters, the iostat utility printed a redundant new line character, making its output less readable. This bug has been fixed and now, no extra characters are printed if a long device name occurs in iostat output.
