Problem
In yml file, data with escape string getting addition escape.
for example,
in system.date.yml we got:
html_datetime:
name: 'HTML Datetime'
pattern:
php: 'Y-m-d\TH:i:sO'
intl: 'yyyy-MM-dd\Tkk:mm:ssZZ'
When dumper copies this to active folder it changes above to:
html_datetime:
name: 'HTML Datetime'
pattern:
php: 'Y-m-d\TH:i:sO'
intl: 'yyyy-MM-dd''Tkk:mm:ssZZ'
in html_datetime.pattern.intl is wrong in active.
