Subject: [PATCH 2/2] Define and use \qtco{} to cover string containing breakable sequence
Fix problematic behavior of \qco{}, whose width estimation is
affected by our breakable sequences of characters "->" and "_".
The issue was once fixed by commit 99b31e87fd0d ("Improve definition
of \nbco{} and \qco{}"), but it has been reverted because "examplep"
package has lost compatibility with up-to-date TeX Live.
This commit works around the issue by defining another macro
"\qtco{}" and using it instead.
Hopefully, we can revert both of the commits when examplep restores
its compatibility.
