By now I've become so accustomed to just copy the bold text from the line above it and paste, that it doesn't break me out anymore. I know I should concentrate and type it out, but in my head it has just become visual noise and a boring exercise.
Aha .. perhaps the interface can be changed to prevent copy-paste into that field.
Better would be to not show the repo name directly above the dialog at all so the user actually has to think a bit about what they need to enter. Just re-typing a text shown to you can be done on autopilot as well.
