bug#33563: 27.0.50; Autoload generation during package installation pollutes recent-files list

[Clément Pit-Claudel]

Hi all,

Generating autoloads as part of installing a package creates an entry in the 
recentf list.  For example, if I start emacs -Q, run M-x recentf-mode and M-x 
package-install RET company RET, then run M-x recentf-open-files, I see this:

  [1] /build/emacs/melpa/sandbox/elpa/company-20181105.2312/company-autoloads.el

This minor annoyance becomes more problematic when updating a large number of 
packages; here's how my recentf list looks after doing an update and browsing a 
few files:

I presume the fix would be to make sure that autoload-find-generated-file does 
not call find-file-hook?

Cheers,
