`-e` terminal flag is hardcoded in

[thacuber2a03]

this is done on the basis that xterm exists on the system and will be used to execute a command
I don't have xterm, I have gnome-terminal, and in there -- COMMAND is preferred over -e=COMMAND

Fixed with ee55f7c.

Default is now set to { "xterm", "-T", function(target) return target.name end, "-e" }.

To make it work with gnome-terminal, you'd set it to

{ "gnome-terminal", "-e" }

or, I guess you could probably do

{ "gnome-terminal", "--" }
