beautifygraph: change the current commit symbol...
beautifygraph: change the current commit symbol The existing "circle with vertical fill" character renders as full width in many terminals making the beautified symbols have uneven size. Additionally, the proposed "fisheye" character is the logic 'active' version of the current merge symbol, "bullseye." Differential Revision: https://phab.mercurial-scm.org/D9678
