report_host() does not expect a DNS name, but an IPv4 or IPv6 address.
In many cases, an SVN password is going to be associated with only a
hostname.
This may be a bug in report_host -- it's certainly inconveninent.
However, we don't usually wnat report_host to be making tons of DNS
lookups when importing hosts, so this forced step is likely intended.
Also, begin/rescue/end blocks that don't hint at what errors are
intended to be caught are rarely a good idea, so this at least informs
the user which exception was raised.
