please squash the commits

should just have one

pythonPackages.pyezminc: 2017-08-29 -> 2019-07-25

[bcdarwin]

Only make a single commit for these two packages?

[jonringer]

correct, it will also be easier to cherry-pick if it's a single commit

please edit the commit subject to be : pythonPackages.pyezminc: 2017-08-29 -> 2019-07-25

[bcdarwin]

But that's not the change that has been made (pyezminc's version wasn't changed).

[jonringer]

oh wow, it looked like the same file to me when I was reviewing... So sorry, yes, please have 1 commit per package. you probably had it right the first time. I apologize
