Fix handling of known hosts files starting with ~.

Browse Source 
https://bugzilla.redhat.com/show_bug.cgi?id=541423#c3

Done by adding the eval back.  The only thing that this breaks AFAIK
is handling of known hosts filenames that have more than one
consecutive space in them, but I couldn't figure out how to get both
to work and IMO support for files starting with ~ is much more
important.
