A couple items on TODO

As I was browsing TODO, I noticed a couple unassigned items that I may be 
able to help with (I haven't worked with the source before):

*Add use of 'const' for variables in source tree
*Convert remaining fprintf(stderr,...)/perror() to elog()

Neither seemed to be active at all.

I also noticed that this item has been there for a while:
*Encrpyt passwords in pg_shadow table using MD5 (Bruce, Vince)

Are the mentioned people actually working on the last item?

All of the items seem to be simple and seperated enough that I might be able 
to learn the source as I go. I can see how the last one might be more 
difficult, but I don't know. As goes without saying, I really don't know much 
about postgres, so any kind of schedule is completely unknown. For a cursory 
glance, I used the postgresql-7.1beta6 source, but I will grab the latest to 
actually work on.

Any input about the difficulties or affected areas of code would be 
appreciated. I suppose if the items made it to TODO, they will take more than 
a couple minutes to fix.
