Alois Klink	59c69600e8	fix(git): support single character branch names In gitGraph, add support branch names that only have a single character. The branch regex is checking for a starting character, and an ending character, so it currently needs at least two characters. I've wrapped everything except the first character in a `()?` to fix this. There are some really complicated regexes that do match what valid git branches are (see https://stackoverflow.com/a/12093994), but I'm reluctant to add them in, since it will be a pain to test all the different edgecases. Hopefully https://github.com/mermaid-js/mermaid/pull/3432 might be used in the future to make a better gitgraph parser!	2022-09-15 01:05:11 +01:00
