Incorrect tags used in documenting functions

In the file cyacas/libyacas/include/yacas/patterns.h around the lines 180 we see:

    /// - If \a aPattern is a list of the form <tt>( _ var )<tt>,
    ///   where \c var is an atom, LookUp() is called on \c var. Then
    ///   the correspoding MatchVariable is constructed and returned.
    /// - If \a aPattern is a list of the form <tt>( _ var expr )<tt>,
    ///   where \c var is an atom, LookUp() is called on \c var. Then, 

I think this should read:

    /// - If \a aPattern is a list of the form <tt>( _ var )</tt>,
    ///   where \c var is an atom, LookUp() is called on \c var. Then
    ///   the corresponding MatchVariable is constructed and returned.
    /// - If \a aPattern is a list of the form <tt>( _ var expr )</tt>,
    ///   where \c var is an atom, LookUp() is called on \c var. Then, 

i.e.:

• the change <tt> to </tt> on 2 places
• correspoding -> corresponding
