[0.14.22] Cannot save game as "nul"

[ludolpif]

Hi,

I noticed that I cannot save a game if I choose "nul" as it's name.
I use steam version on Windows 7 64bits.
The same bug was seen on a standalone 0.14.16 on the same OS.

Steps to reproduce :
1- start a free play mode new game
2 - go to save dialog
3 - type nul as the name
4 - push the save button

What I obtain :
Error message box : Notice / Failed to rename file: C:\Users\lpouzenc\AppData\Roaming\Factorio\saves\nul.tmp.zip. It might be locked by other application.: operation not permitted.

What I should obtain :
A successfully saved game entry.

Please find a screenshot attached.

"nul" is an invalid file name on Windows: https://www.google.com/search?num=40&si ... oARu11_IeU

There's nothing we can do about that - pick another file name.
