Description of problem:
When reporting the current disk status, the zz-disk_space utility does:
df -h | grep '^/dev/'

However, df sometimes reports the partition usage on two lines, e.g.:
/dev/mapper/Volume00-LogVol00
                      112G   65G   43G  61% /database

Thus the mailed report only contains the first line, which is not very useful...

Version-Release number of selected component (if applicable):
logwatch-5.2.2-1

How reproducible:
Always, if you have a long path to the device entry

Steps to Reproduce:
1. Create a partition with a long path for its device name
2. Mount it
3. Wait for logwatch's email
  
Actual results:
/dev/mapper/Volume00-LogVol00


Expected results:
dev/mapper/Volume00-LogVol00
                      112G   65G   43G  61% /database


Additional info:
I'd suggest removing the "|grep" part...  or using df -hl (or -hP, because
the P seems to force the output on a single line).
