[Mattias Engdegård]

branch: master
commit 4fc84cb23b6d671b44f18b8462e94c3bcfc3ee09
Author: Mattias Engdegård <mattiase@acm.org>
Commit: Mattias Engdegård <mattiase@acm.org>

    Only call set-text-conversion-style if it exists
    
    * lisp/auth-source.el (read-passwd): Guard call, as it was before the
    code was moved here.
    `set-text-conversion-style` is not present in all configurations.
