Find/Raplace doesn't match everything.

[Jakub Ś]

Steps To Recreate:

1. Open replacebycode sample
2. Switch to source and pase:

   <p>This is an example [<a href="http://bbc.co.uk">click</a>] of linked text.</p>
   

3. Copy the whole line and paste 4 or so times into the page.
4. Click the Find/Replace button, and select the replace tab.
5. In the "Find what:" type "[click]". Do not type anything into the "Replace with:" text box.
6. Click "Replace All".

Result: The find and replace tool only replaces one match when you choose "replace all".
