In its "shell history anomalies" part chkrootkit collects two lists of
anomalous history files:
- $files: file size is zero
- $files1: is linked to another file
But when the according warning is written both times $files is used.
For details see the attached diff.
Reproducible: Always
Steps to Reproduce:
None of the files target, .link-history and .empty-history should exist.
1. echo Hallo > target
2. ln target .link-history
3. touch .empty-history
4. chkrootkit
