error when no new line at end of .ssh/config

[fredericrous]

Hey! First of all thank you for this tool. There are lots of bookmark managers for ssh, but it's the first one I find that does exactly what I want, be simple and :

• command line
• cross platform (we're almost there)
• does not need extra framework like ruby or node
• comply with ssh config standard

I noticed an issue. If I edit the config file myself and forget to add extra new line at the end of the file (yeah I should use a better text editor),
Then I got this error (on macos):

panic: runtime error: invalid memory address or nil pointer dereference [recovered]
	panic: runtime error: invalid memory address or nil pointer dereference
