Hilight Toggle Error when Default Load Disabled

[jebaum]

If signify is disabled from starting by default, with let g:signify_disable_by_default = 1, calling :SignifyToggleHighlight before calling :SignifyToggle produces this error:

Error detected while processing function sy#highlight#line_toggle:
line 6:
E121: Undefined variable: g:signify_line_highlight
E15: Invalid expression: g:signify_line_highlight

The error goes away once :SignifyToggle is called once. Ideally I guess highlight should check to see if signify is disabled for the current buffer, and if it is, enable it.

It may be worth noting that when working with a file with zero modifications, calling highlight will always produce the above error, even after running toggle.

I never had that problem because I explictely set g:signify_line_highlight to 0 in my vimrc.

Thanks a bunch for the feedback!
