I'm skeptical about this.

First, there are multiple commenting styles.  The end-of-line style is 
less common in my experience, because pg_hba.conf lines tend to belong. 
Another style is

# foo
host db jim 127.0.0.1/32 md5
# bar
host db jim 127.0.0.1/32 md5

or even as a block

# foo and bar
host db jim 127.0.0.1/32 md5
host db jim 127.0.0.1/32 md5

Another potential problem is that maybe people don't want their comments 
leaked out of the file.  Who knows what they have written in there.

I think we should leave file comments be file comments.  If we want some 
annotations to be exported to higher-level views, we should make that an 
intentional and explicit separate feature.
