Unstable sha commit length

[mutalimov95]

Sometimes when I use {commit} in format I get 8 characters length (in many cases I get 9 characters length).
I don't know why this is happening and how to predict the length of the sha.

Dunamai just takes the hash returned by the VCS tool (e.g., git log -n 1 --format="format:%h"), so it's up to the VCS. For example, using Git, I get 7 characters in the Dunamai repository as well as in a new repo with one commit, but I get 8 characters in a repository with over 2,000 commits, so I think it gradually increases the length to avoid collisions.

The next release will provide a --full-commit option so that you can always get the full hash.
