[foldcode addon] Change arrow appearance when a single line is collapsed

Sam Wilson · marijnh · commit 431dd1b16818 · 2016-06-03T22:55:16.000+02:00
Use findMarks instead of findMarksAt in foldGutter.js to correctly
find marks when a single line is collapsed so that the arrow displays
correctly as collapsed.
