[ruby/rdoc] Support crossref of methods with multiple arguments
For example, consider the following markup:
C1#m(a, b)
Before this patch, it generated this HTML:
<p><a href=\"C1.html#method-i-m\"><code>C1#m</code></a>(a, b)</p>
Which places the method arguments outside of the link.
Now it generates this HTML:
<a href=\"C1.html#method-i-m\"><code>C1#m(a, b)</code></a>
