[AUCTeX] Auto file parsing and multifiles

[Robert P . Goldman]

I have been having troubles editing some of my latex files that are parts of
multifile documents, because I'm not getting the macro support I expect.

E.g., I have a file, foo.tex, that's part of a document that is in main.tex.
main.tex is recorded as the master of foo.tex.

Now, when I am editing foo.tex, auctex is loading neither auto/main.el nor
style/main.el.  Am I doing something wrong here, or is this the behavior I
should expect?

If I am NOT doing something wrong, is there something I can do to persuade
auctex always to load the .el files for the TeX-master?

thanks!
