We validate length to be [max 160 chars per line](https://github.com/Elgg/Elgg/blob/1.9/.scripts/ElggCommitMessage.php#L128), but your build script [truncates to 80 chars](https://github.com/Elgg/conventional-changelog/blob/master/lib/git.js#L115).

This commit is truncated to 80 chars, not 100.

I say we increase limit in build script to match value we use for validation.
