Commit 225dd3f7316ad8a18454aee499795433656c1615
2018-11-29T14:07:27
Scheme improvements (#1556) 1. `)` is part for symbols (strings). 2. Function names which have a keyword/builtin as a prefix are not matched correctly. 3. Zero-length function names. 4. `'` is highlighted as `string` even if it marks a list. Also add support for Scheme characters.
