Description of problem:
The dd_rhelp helper script for dd_rescue uses the deprecated "tail +2" form;
needs to be "tail -n +2"

Version-Release number of selected component (if applicable):
dd_rescue-1.12-4.fc6

How reproducible:
For recent versions of GNU coreutils

Steps to Reproduce:
1. dd if=/dev/zero of=badimg bs=1k count=1000k
2. dd_rhelp badimg badimg.rescued
3. Ctrl-C or Ctrl-\ and goto 2.
  
Actual results:
The script appears to still work, but with the following errors sprinkled
throughout:
/usr/bin/tail: cannot open `+2' for reading: No such file or directory
/usr/bin/tail: cannot open `+2' for reading: No such file or directory

Expected results:
No complaints from the tail util.
