extract: add extract_finish_wide(), and optionally skip stripping trailing empty cells

Browse source 
extract_finish() returns the extracted text in UTF-8, while
extract_finish_wide() returns the extracted text in Unicode.

This patch also adds a new argument to extract_finish{,_wide},
that when set to true, skips stripping trailing empty cells.
