git log --pretty=format joins lines in the subject of commit message

Commit something to a git repository with a commit message with several newlines like this:

==== commit message starts below === first line second line third line

fifth line === commit message ends above ===

Git treats the first 3 lines as commit message subject and the last line as its body.

'git log' shows the commit message correctly - exactly like I've entered. So does 'git log --pretty=raw'

But 'git log --pretty=format:%s#%b' joins the first three lines: first line second line third line#fifth line

Is it a bug or a feature? If it is a feature how can I acquire the original subject of the commit message by using custom format?

Thanks a lot.
