How to select what NERDTree window Vim focuses on depending whether a file is passed

Question

I currently have the following in my .vimrc:

au VimEnter * NERDTree
au BufWinEnter * NERDTreeMirror

This I believe launches NERDTree when I open Vim, as well as when I open a new tab using a plugin. Currently, when I launch Vim using

vim

at the command line, the cursor is sitting in NERDTree ready for me to navigate my files, which is great. However, when I use

vim my-file.txt

the cursor remains in the NERDTree window. I'm aware that I can add this to my .vimrc:

au BufNew * wincmd l

But that means the cursor will always be placed in the window to the right of NERDTree, even if I don't specify a file.

Does anyone have any ideas?

You can make the command conditional on whether arguments were passed to Vim:

:au VimEnter * if argc() > 0 | wincmd l | endif

(I'd use the VimEnter event for that; just make sure this autocmd comes after the one that opens NERDTree.)
