conflict with "Ctrl + R" in Mac/Linux/..

[Cxj2016]

I made a push a moment ago using "git push origin xxx" in command line,then if I want to push again, I like to use "Ctrl + R(reverse-i-search) " to get the push history. When I find it ,however, if I press "Tab", the command will be "git push push origin xxx",so I need to clear the repeated 'push' to make a success push!
Have a look,guys,thank you~
