The last changes in the LaTeX Bundle broke down syntax coloring for things like this: $D_1={x_1^2}$ Basically, the { inside math mode is considered constant.language.generic while the } is not. The relevant code is { name = 'constant.language.general'; match = '\([^a-zA-Z]|[A-Za-z]+)(?=\b|}|]|^| _)'; }, Can't see right now what the problem is with it, maybe someone else can spot it. Thanks.
