◆ doEdgeSlide()

static void doEdgeSlide	(	TransInfo *	t,

Implementation note, even mode ignores the starting positions and uses only the a/b verts, this could be changed/improved so the distance is still met but the verts are moved along their original path (which may not be straight), however how it works now is OK and matches 2.4x - Campbell

Note: len_v3v3(curr_sv->dir_side[0], curr_sv->dir_side[1]) is the same as the distance between the original vert locations, same goes for the lines below.
