The method FindReplaceDocumentAdapter.escapeForRegExPattern(String), when handed a character less that \x20, will often escape that character using the \xhh format.  However, if the leading digit is a 0, the 0 will not be included in the escaped string.

This leads to at least one defect in the base eclipse experience described below... plus my product is re-using this method so it would help my product to also fix this

Reproducible: Always

Steps to Reproduce:
1.Open a text editor
2. Engage find / replace
3. Enable regular expressions
4. Replace a character in your file with the escape sequence \x08
5. Now that character is in your text file
6. Close find \ replace
7. Select that character in the text editor
8. Re-engage find \ replace.
9. The Find dialog appears with the value \x8 in the Find text field.

\x8 is not a valid regular expression escape sequence, so pressing find will give the user an error message saying as much.
