[nongnu] elpa/geiser 47bb86d682: make autoloads more lazy (Stefan Monnier)

[ELPA Syncer]

branch: elpa/geiser
commit 47bb86d6829ffa81ec021ee6217379b216d95bfc
Author: jao <jao@gnu.org>
Commit: jao <jao@gnu.org>

    make autoloads more lazy (Stefan Monnier)
    
    Thanks to Stefan's patience and actual implementation, we now don't load all
    of geiser-impl.el and its dependencies just because there's a call
    geiser-activate-implementation in geiser-<impl>-autoloads.el.
