[rancid] Fortigate diffs when nothing actually changed

[Robert Drake]

Try running the diff on the cli and check whitespace?  Diff is a pretty 
base-level thing, so it's not rancid that's tripping but something in 
the actual config which makes it see a difference, but it's something 
that doesn't show up on-screen.

If it is whitespace then there might be an error in the rancid script 
that parses lines and adds a space, or there might be something in the 
router that leaves whitespace where it shouldn't. Either way, it should 
be correctable by having the rancid script remove the offending stuff.
