`sage -upgrade` downgrades from 4.6 to 4.6.rc0
I tried to run
sage -upgrade from a built-from-source installation of 4.6. Nothing seemed to happen, but now when I run
sage, I get a warning telling me I'm running an unstable prerelease version, and the header says "Sage Version 4.6.rc0"! I checked
$SAGE_ROOT/devel/sage/sage/version.py, and in that file the version is duly listed as 4.6. Any idea what's going on?
The files at
$SAGE_ROOT/local/bin were marked as parented to the 4.6.rc0 revision of the hg repository for some reason. Thus
$SAGE_ROOT/local/bin/sage-banner had been replaced with the 4.6.rc0 banner. I had committed a revision to 4.6 before running
sage -upgrade, so this may have somehow been responsible. Still, I'd appreciate it if someone else could test this.
