[gentoo-dev] [PATCH subversion.eclass] Export working copy information after the update.

[Michał Górny]

Currently, subversion.eclass exports working working copy information
such as ESVN_WC_REVISION two times: once before running 'svn up',
and the second time in pkg_preinst(). As a result, between those two
calls ESVN_WC_REVISION lists the *previous* working copy revision rather
than the current one.

This behavior is not exploited by any ebuild. Instead, all ebuilds that
use ESVN_WC_REVISION either hack it around, or actually use the wrong
revision mistakenly.

The patch fixes the eclass to export working copy information *after*
the update is done. Redundant call to subversion_wc_info is removed from
pkg_preinst() as no ebuild needs the re-export.
