ehh...probably. The PR has a point as `sed --help` (v4.2.2) does not list
the `-E` option.
If we want to be super safe we could check that `sed -r` is supported and
use `-E` as a backup.

@zentol What do you think? Is this safe to merge?

@zentol thx for comment.
I checked my system SUSE 11 SP4(which is a wildly used version),sed version
is 4.1.5,and it do not support '-E'. I don't konw how many linux version use
sed 4.1.5.

Not sure about this one, after all `4.2` is already _9 years old_.
