Old description

The version format for virtual packages (YYYYmmdd.HHMMSS) doesn't include a pkgrel like packages normally have (<pkgver>-r<pkgrel>).

This creates ambiguity in the output of the apk list command. Normally it is enough the strip the last 2 dashes but that doesn't work with the version format of virtual packages:

• <pkgname>-<pkgver>-r<pkgrel>
• <pkgname>-YYYYmmdd.HHMMSS

I suggest adding -r0 to the version of virtual packages app_add.c#L118. !132 (closed) does fix the apk list problem too but a consistent version format would still be better.
