Info v.s. Debug output

It seems that Feedback.msg_debug messages go to the Debug “view” of the Output tab, while Feedback.msg_info go to the Info “view”.

I’ve two problem with this:

• the two class of messages are decorrelated by this presentation: a debug message may arrive before or after an info one, and you don’t know
• at least in my setup, the Debug “view” takes precedence over the Info one and this is bothering me on normal use: if there is anywhere a debug message, then the infos are not shown (you need to click after every interaction with Coq).

I can imagine two improvements:

• an option to merge the two views (or merge then and have an option to hide/show debug stuff)
• make the user choice about the preferred view take priority over the last-updated view

After some offline discussion, we agreed that two improvements could be made:

• Output generated by commands in the document should be attached to their location of origin.
• Some specific views may be needed for trace-like information
• The output panel should not be used much for standard activities, maybe just for debugging

We discussed this on gitter, and we seemed to agree a temporary measure meanwhile could be nice. Also for old Coq versions!

We also debated (but didn’t reach agreement) on whether "X is definedshould indeed be Info-only, sinceXmight not appear in the source, e.g.Inductive foo := .generatesfoo_ind` etc. But that’s a separate question anyway, and I’m not so sure myself.

EDIT: Also, for now I’m happy reverting #35 locally.
