@is_suffix(s1:string, s2:string)
@is_suffix(s1:string, s2:string, cmp:fct)
@is_suffix(t1:tab, t2:tab)
@is_suffix(t1:tab, t2:tab, cmp:fct)
@is_suffix is an overloaded function. See also the functions @is_subsequence and @is_prefix.

@is_suffix(s1:string, s2:string)
the predicate returns true if string s1 is a suffix of string s2.

@is_suffix(s1:string, s2:string, cmp:fct)
the predicate returns true if string s1 is a suffix of string s2 where the characters are compared with the function cmp. The characters are passed to the function cmpq as strings of length one.

@is_suffix(t1:tab, t2:tab)
the predicate returns true if the sequence of elements of t1 is a suffix of the sequence of element of t2.

@is_suffix(t1:tab, t2:tab, cmp:fct)
same as the previous version but the function cmp is used to test the equality between the elements, instead of the usual comparison between values. For example: 
       @fun_def cmp($x, $y) { $x < $y }
       @is_suffix([1, 2], [5, 6, 7], @cmp) ->true
true is returned because @cmp(1, 6) and @cmp(2, 7) hold.

(t1:tab, t2:tab, cmp:fct): same as the previous version but the function is used to test the equality between the elements, instead of the usual comparison between values. For example:

            @fun_def cmp($x, $y) { $x < $y }
            @is_suffix([1, 2], [5, 6, 7], @cmp) ->true

is returned because and hold.
