make the 'identify' command assume that a single decimal number is not an address (allowing it to be handled as a user id). qcc: support default initialisers in function calls. tweak filesystem code to try to flush individual files instead of discarding the entire fs hash. fix 'snap' stuff. other tweaks... git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5058 fc73d0e0-1445-4013-8a0c-d673dee63da5
