Bug 491764 – euse does not correctly handle package names containing numbers

• Status: CONFIRMED
• Product: Portage Development

[Description Yuri Shatroff 2013-11-20 13:06:09 UTC]

When invoking `euse -p` with a package name containing a number, e.g. sys-fs/lvm2, euse fails with an error: Invalid package atom.

# euse -p sys-fs/lvm2 thin
ERROR: Invalid package atom. Did you forget the leading '='?

Other gentoolkit tools e.g. equery, epkginfo do handle such names correctly.

Looks like an issue with the regex. This fixes it:
