Summary

Under PHP 8.1, PhabricatorEditorURIEngine::newForViewer() is throwing a trim(NULL) error when trying to view a diff.
This is because it tries to apply string operations to a user setting which will be null by default.

Fixes T15518

Since we are not interested in knowing the length of the string. Also note that trim() always return a string, and never NULL.

Premising that your addition of $pattern === null is perfectly OK ✅

Thanks :) Soft +1 to wait for other thoughts. The test plan works for me.

Personally I will hard+1 if we get rid of that strlen() since we have that possibility here, and it's not such a frequent possibility.

Nice - complete removal of that strlen as suggested.
