Description
Fastfetch does not display the name of the terminal emulator correctly, if the emulator was installed through nix and has a particularly long name. So far I've found that this effects the Gnome, Xfce and Mate terminals, which display as follows:
Terminal: .gnome-terminal
Terminal: .xfce4-terminal
Terminal: .mate-terminal-
Note the leading period, and the trailing dash in the case of the Mate terminal.
For comparison, on Debian these display as:
Terminal: GNOME Terminal 3.56.2
Terminal: xfce4-terminal 1.1.4
Terminal: mate-terminal 1.26.1
