Undefined variable in vim netrw when netrw_browse_split = 3

[Bogdan Harjoc]

To reproduce, open the netrw explorer in a new tab, and set opened files to go to a new tab:

:let g:netrw_browse_split = 3
:Texplore

When the user selects a file from the explorer with Enter, this error appears:

Error detected while processing function <SNR>20_NetrwBrowseChgDir:
line 135:
E121: Undefined variable: b:netrw_curdir

And this is displayed for a second:

Invalid arguments for function SetRexDir

Saw this after upgrade to Ubuntu 16.04 (vim 7.4.1689-3ubuntu1.2). The error didn't show with vim 7.4.052-1ubuntu3.1 on Ubuntu-14.04.
