#99 Replace all infinite loop

[Brian Nelson]

When checking a document, if you choose to Replace all

occurances of a word with the same word, aspell enters
into an infinite loop. The expected behavior would be
to either silently ignore the request, complain then
ignore the request, or to comply with the request but
stop when the replacement wraps back to the starting point.

Attached patch fixed it by ignoring the request. Changes
will appear in Aspell 0.60.1.
