[docs] regular expression documentation bug

[Alexandros Marinos]

In the page http://docs.python.org/library/re.html, section 7.2.1, it says:

'$'
Matches the end of the string [...] foo matches both ‘foo’ and
‘foobar’, while the regular expression foo$ matches only ‘foo’.

this last sentence looked odd, so I tried it:

print re.match('foo$', 'foobar')

output: "None"

I think a better example would be something like 'foobarfoo'.
