Had encountered this problem too.
Tried the following in alerts.actions.conf but to no avail
include.results_link = 0
include.view_link = 0
Same results in savedsearches.conf
action.email.include.results_link = 0
action.email.include.view_link = 0
Had to resort to changing $SPLUNK_HOME/etc/apps/search/bin/sendemail.py
Comment out the line that calls "htmlMedaDataViewTemplate()"
