why won't e.g., [[commons:Bla]] become a blue interwiki link instead of a red local link?
By the same reason it's not on the sidebar at wikimedia wikis.
make sure that the commons: prefix is actually in your interwiki table
Yes, table wiki_interwiki has it, from $ grep commons mediawiki-1.11.0/maintenance/interwiki.sql ('commons','http://commons.wikimedia.org/wiki/$1%27,0),
If that 0 were a 1 it would be in the sidebar instead of inline.
