Don't omit <marker> event for words which are recognized as pairs (such as "of the"). Lang=Spanish, fix missing "y" in numbers such as "21". Lang=EN-US, Don't add 'intrusive r' between phoneme [i@] and a following vowel. git-svn-id: https://espeak.svn.sourceforge.net/svnroot/espeak/trunk@268 d46cf337-b52f-0410-862d-fd96e6ae7743
