| User reported a regression between 2.26 and 2.36 |
| when trying to .dot the following graph: |
| |
| digraph g { |
| 1 -> 2 [label="\\"] |
| } |
| |
| 2.26 shows it as '\' while 2.36 fails as: |
| $ dot -Tpng a.dot -o a.png |
| Warning: 1.dot: syntax error in line 2 near '' |
| |
| Thanks to Ulya Trofimovich who found and bisected |
| the problem down to this commit, which fixes problem |
| only in git version. |
