Description
Script management loses sync when Isabelle -> Settings -> Use Linear Undo is disabled.
Seems to be partly to do with regexp matching, but also a fault in counting.
Note: See
TracTickets for help on using
tickets.
Can't duplicate now, likely to do with changing undo mechanism during scripting. Added call to
proof-deactivate-scriptingwhen changing undo mechanism to encourage completing/emptying the buffer and give a warning if this isn't done.
