[PATCH] Add a subject indicating that the commit message is empty

[Nezmer]

Before this patch:
If the commit message is empty, we would have this html:
<a href='path'></a>

It's impossible to go to the commit page without viewing the source or
using hints (e.g vimperator).

After applying this patch:
A gitweb-like "(no commit message)" would be displayed as a commit
subject.
