Subject: [PATCH] Make it possible to subtract conditions from debug=
|
|
|
|
This makes it so you can do set debug to "all,-scripting,-lexer" and get the
|
|
obvious outcome. Any negation present will take preference over that
|
|
conditional, so "all,-scripting,scripting" is the same thing as
|
|
"all,-scripting".
