@pollydrag your PR is perfect but please add a change-note

[webknjaz]

(@pollydrag this means that you need to add a file to CHANGES/ folder)

@webknjaz @asvetlov Change-note done. Sorry for delay

[asvetlov]

thanks!

[webknjaz]

This is out of order. T U V W X Y Z

[asvetlov]

Good catch!
Fixed by f6b81b3

[pollydrag]

My bad, sorry

[webknjaz]

We probably need to lint that :)

[pollydrag]

I think linux sort can be used for this.
For example, the check might look like LC_ALL=C sort -c CONTRIBUTORS.txt
But first you need to make it sorted: LC_ALL=C sort -o CONTRIBUTORS.txt CONTRIBUTORS.txt

First line may be changed as - Contributors for keep sorting

[asvetlov]

I don't care too much -- but if somebody want to make a PR for this you are welcome
