Hi,

Attached is a small patch for the file functions.sh (part of baselayout)
which implements the feature "emergemail" (set in /etc/make.conf FEATURES).
When this feature is turned on (and an mta is present), all einfo, ewarn,
and eerror messages are emailed to root.

This is useful if you upgrade or install multiple packages at once, and you
don't want to miss any important messages that go whizzing by.

There is a major flaw with the current implementation.  Namely, you get an
email for _every_ invocation of einfo, ewarn, or error.  The way those
functions are commonly used (repeated calls for multi-line messages) makes
avoiding this flaw quite difficult without rather sweeping changes to the
design of emerge/ebuild.

Comments or suggestions welcome.
