#588 Fix delimiter select crash

[Andreas Jonsson]

https://sourceforge.net/p/notepad-plus/bugs/4864/

Set the delimiters to the same character, such as an apostrophe. Then Ctrl+DblClick in an empty document will cause a crash.

Documents like this can also cause crashes:

a

b

Note that the middle line contains a single space. Ctrl+DblClick in the middle line will cause a crash.

This patch is similar to revision 1059.

Disregard the above patch. It breaks the case when you have the left delimiter as the first character, like:

' test test '

Use NppNotification2.cpp.patch instead.

I cannot absolutely reproduce the crash.
Am I missing somethings?
