* lisp/outline.el (outline--fix-buttons-after-change): Add save-match-data.

Browse source 
It's important for a hook in after-change-functions not to change match-data.
Otherwise it breaks functions that make changes in the buffer, such as
for example, successive calls to delete-region in smerge-keep-n, etc.
