(Suggestion) When installing a style as a userscript, its @-moz-document rules to be converted to @include rules

[darkred]

My suggestion (if possible):
when installing a style as a userscript,
its @-moz-documentrules^[1], to be converted to separate @include rules.
This way, the userscript will execute only if it matches any of those rules, just like the initial style.

Example:

@-moz-document url("stackexchange.com"),
               url-prefix("http://superuser.com"),  
               domain("serverfault.com"),
               regexp("^https?:\\/\\/((chat|meta|ja|pt|ru)\\.)?stackoverflow\\.com.*")

to be converted in the installed userscript into:

// @include    http://stackexchange.com/
// @include    http://superuser.com/*
// @include    http://*.serverfault.com/*
// @include    /^https?:\/\/((chat|meta|ja|pt|ru)\.)?stackoverflow\.com.*/

Thank you
