SYNOPSIS
string or_bits (string str1, string str2)
DESTRIPTION
<str1> and <str2> are both bitstrings. The result of the function
is a bitstring with the binary-or of <str1> and <str2>,
ie. a string in which a bit is set if the corresponding
bit in <str1> or <str2> (or both) is set.
EXAMPLES
string s1, s2, s3;
s1 = set_bit("", 3); s1 = set_bit(s1, 15); -> s1 is "( ("
s2 = set_bit("", 3); s2 = set_bit(s2, 4); -> s2 is "8"
s3 = or_bits(s1, s2);
-> s3 is now "8 (", ie. a bitstring with bits 3, 4 and 15 set.
