MERGED: Make ":" in GHCi repeat the last command
Ian Lynagh <firstname.lastname@example.org>**20071124231857 It used to be a synonym for ":r" in 6.6.1, but this wasn't documented or known about by the developers. In 6.8.1 it was accidentally broken. This patch brings it back, but as "repeat the last command", similar to pressing enter in gdb. This is almost as good for people who want it to reload, and means that it can also be used to repeat commands like :step.
