Just loading recent files from session file

[Claudius42]

First of all: Great plugin!

1. I like to start vim without any arguments in a folder that already contains a file 'session.vim'. Current behaviour: workspace is correctly reloaded and there is an additional empty buffer opened. It would be great if in this case no empty buffer would be created!

2. I use the plugin 'fholgado/minibufexpl.vim' and it is normally opened. This causes an error message when I start vim since I use your great plugin: "A buffer with this name already exists." Do you have any idea how to solve this issue?
