Good change. But I have a feeling this might trigger some hidden bugs in various repos. |

Fix #1414
The core issue is that
A Bgot turned into/{A}{B}/instead of/(?:{A})(?:{B})/. Most of the time, this doesn't matter, however ifBis a manually defined regex, for example/c|d/, the overall regex ended up being/ac|d/, which ofcourse means something else than the BNF was supposed to express.This is technically a breaking change if people were relying on this buggy behavior.
