/*

This script adds 0.1em of padding around apostrophes ('') in
diffs, to ease distinguishing them from quotation marks ("). See
[[Wikipedia:Village pump (technical)/Archive 139#Is there a better way to illustrate a " --> '' change in the diff view?]].

Install by adding the following row to your [[Special:MyPage/common.js]] or [[Special:MyPage/skin.js]]:

importScript('User:SiBr4/DiffApostrophes.js');
