* /etc/skel/.zshrc:
- added alias hidiff (highlight important stuff in diff
output), active if histring is available
+ - added some isgrmlsmall checks, thanks Frank Terbeck!
- added power completion, thanks wuehlmaus!
See http://zshwiki.org/home/examples/zleiab for details.
Notice: this deactivates the global aliases by default now,
