userdiff: support Java sealed classes A new kind of class was added in Java 17 -- sealed classes.[1] This feature includes several new keywords that may appear in a declaration of a class. New modifiers before name of the class: "sealed" and "non-sealed", and a clause after name of the class marked by keyword "permits". The current set of regular expressions in userdiff.c already allows the modifier "sealed" and the "permits" clause, but not the modifier "non-sealed", which is the first hyphenated keyword in Java.[2] Allow hyphen in the words that precede the name of type to match the "non-sealed" modifier. In new input file "java-sealed" for the test t4018-diff-funcname.sh, use a Java code comment for the marker "RIGHT". This workaround is needed, because the name of the sealed class appears on the line of code that has the "ChangeMe" marker.
