breaks NERDTree plugin

[gmerzu]

Commit 'bcada' breaks NERDTree in the following case: when run Vim with a directory as an argument, such as vim some_dir NERDTree doesn't became active as it should (NERDTreeHijackNetrw is on).

Also I found next bug: With vim-startify plugin and no NERDTree, neither Netrw nor file:line don't work. Probably this one is connected to startify, but the strange thing is that with both plugins: startify and NERDTree, and the commit reverted everything works.

I have the same issue, and I fixed here https://github.com/ldong/file-line.

@bogado I made a PR here, https://github.com/bogado/file-line/pull/55. Thanks.

I can still verify that bug.
