[Bug 923525] [NEW] aptitude safe-upgrade attempts to install both "or" (|) dependencies

[Threepin]

Public bug reported:

In bash I used the aptitude safe-upgrade command to attempt to install
neccessary updates to both an Xubuntu 10.04.3 LTS system with kernel
2.6.31-22-generic and an Ubuntu 10.04.3 LTS system with kernel
2.6.32-38-generic.  Both systems use aptitude version
0.4.11.11-1ubuntu10lucid1.  Amoung the upgrades was the package ubufox
with the new version depending on the package xul-ext-ubufox.  That
package was therefore marked for automatic installation.  It depends on
the package apturl or the package apturl-kde.  The package apturl was
already installed but the package apturl-kde was not.  Aptitude wanted
to install the package apturl-kde and its dependants which numbered in
the seventies.  The command aptitude full-upgrade did not attempt to
install the package apturl-kde or its dependants.  In visual mode
aptitude also did not attempt to install the unnecessary packages.

I expect the safe resolver to be more conservative than the full
resolver.  I expect it to avoid installing and removing packages in an
upgrade.  I expect to be able to use the safe resolver without having to
check if each package is actually needed.  I expect the safe resolver to
parse the "or" symbol (|).
