[elpa] externals/isearch-mb ba14991cb8: Set lazy-highlight-buffer globally

[ELPA Syncer]

branch: externals/isearch-mb
commit ba14991cb81c4fad8e5db54d5233322905a1e3f3
Author: Augusto Stoffel <arstoffel@gmail.com>
Commit: Augusto Stoffel <arstoffel@gmail.com>

    Set lazy-highlight-buffer globally
    
    In the previous approach, the variable was set too late, so the first
    round of lazy highlighting could be incorrect in certain commands such
    as isearch-symbol-at-point.
