Lines starting with '#' will be ignored, and an empty message aborts the commit.
Just don't start your commit message with #
fix bug #2355 of this issues
It's not vim, it's git: according to the documentation:
A '#' or ';' character indicates a comment.
Note that you could change this per repository:
core.CommentChar Commands such as commit and tag that lets you edit messages consider a line that begins with this character commented, and removes them after the editor returns (default #).
