Bug Description

A strange behaviour was noticed over on the forum. It seems after annotation the schematic files contain a link to the cache lib. It seems strange to me that this info is suddenly required after annotation. (I would expect this to either be relevant as soon as the first symbol is added or never.)

My kicad version (same behaviour was also observed in current nightly):

Digging into the code produces this comment from the header parsing routine:

// The next lines are the lib list section, and are mainly comments, like:
// LIBS:power
// the lib list is not used, but is in schematic file just in case.
// It is usually not empty, but we accept empty list.

So it looks like it was added at some point, and has just been there ever since. It appears that it doesn't actually do anything though since it is just skipped in the parser for v5/6 (in fact, everything between the opening line and EELAYER END is skipped, so it could be ignored in current versions without causing problems).

AFAIK, this should not happen. Given that the libraries in the schematic are and have always been ignored I doubt that there is an issue with this.

I'm not sure the annotation is the culprit here. Given that the "LIBS:" section of the schematic header is completely ignored, I'm leaning towards removing the code that saves the "LIBS:" section from the legacy plugin. If no one objects, I will make it so.
