Asterisks in init.ora parameters

Anybody ever seen a init.ora file in an init.ora file that looks like

*.db_block_size=8192
*.db_cache_size=256M

etc?

I've never seen an asterisk and period at the beginning of a init.ora line 
before.

I know this is not a spfile, because 'alter system .... scope=spfile'
command get ORA-32001 errors.  

What is the significance of the asterisk and period?
