:sp file:line closes existing splits

[panozzaj]

Thank you for the plugin! I am loving it, it is very useful for pasting error messages from the console.

I have run into one issue. Finally got around to reducing it to a simple case...

Replication:

• MacVim (version: VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Dec 20 2014 10:38:46))
• given local files one.txt and two.txt with a few lines in each
• $ mvim one.txt
• :sp two.txt:2

Behavior:

• removes one.txt from view and puts two.txt in its place

Expected behavior:

• open two.txt in a new split and keep one.txt open

Notes:

• in the error case above :buffers shows both files, so I think it is not closing the buffer but removing it from view (I don't have a fantastic understanding of the relation of buffer and view, or I could elaborate more. :| )
• if I have one.txt and two.txt open, and try :sp two.txt:3, it correctly opens the split at the right place and does not close the others (three viewports open total)
