DOC BUG QTextCursor incorrectly states charFormat() is format after cursor

The documentation for QTextCursor::charFormat() correctly states "Returns the format of the character immediately before the cursor position()."

However, the introduction of the same document directly contradicts this:

"When we refer to "current character" we mean the character immediately after the cursor position() in the document; ... The format of the current character is returned by charFormat(), "

The intro needs to be corrected.

I suspect this is not the only place in this document that has this problem: there is probably a bigger issue of before vs. after cursors that warrants someone looking through the dox in a more methodical way.
