[Freeciv-Dev] Bug with worklists and auto-upgrading unit targets

[Corin Anderson <corin@xxxxxxxxxx>]

I found a bug with how the worklist code in cityturn.c auto-upgrades unit
building targets.  The idea is to check a unit target for obsolesence; if
it's obsolete, try to target the unit that obsoletes it.  For example, if
the worklist contains an entry for a musketeers, but conscription has been
researched, the worklist should switch to riflemen instead of the
now-obsolete musketeers.

Well, it doesn't do that right now.

I know what's wrong and how to fix it, but I just don't have the time this
evening to code, test, and diff.  I'll send a patch along tomorrow night.

*sigh*
