Bugzilla Bug 162306

For ease of use, genlop should accept '=' prefix when specifying ebuild
versions. Example: I want to emerge a dozen of things, and come with

emerge -vp1 =sys-libs/db-4.2.52_p4 =media-libs/libkipi-0.1.4
=dev-cpp/gtkmm-2.8.3 | genlop -p

but, in order to get details, I was natural for me to ask
genlop -t =sys-libs/db-4.2.52_p4 =media-libs/libkipi-0.1.4 =dev-cpp/gtkmm-2.8.3
(either editing first line, or copy pasting ebuilds), what failed obviously:
!!! Error: no merge found for '=sys-libs/db-4.2.52_p4'
!!! Error: no merge found for '=media-libs/libkipi-0.1.4'
!!! Error: no merge found for '=dev-cpp/gtkmm-2.8.3'

Ok, manually removing the '=' is not so hard for a 3 ebuilds example; but when
the output is a list of >10 names (revdep-rebuild often generated long lists),
or for various other reasons, I think adding support for accepting optionnal
'=' would improove compatibility with emerge, and ease of use, and should not
interfeere with other functionalities.

your actual scenario has been fixed in svn, working on getting -t
=cat/package-version to work as well (simply doing -g cat/package-version
works)

ok, fixed with -t searches as well for exact package names. svn committed.
