Load change in master?

[Ergus]

Hi I just build the master branch and the load time increased a
lot. Looking at the *Message* buffer I see that even with the -Q option
it loads a lot of files (and prints messages) it was not doing that
before:

----------------------------------

Do we really need to load so many languages for example?

My load time increased 4 times even with -Q and no file it takes more
than 2 seconds and before it was actually faster than vim.

What changed?

Best,
