c4d8f27019 Fix compiler warning (-Wchar-subscript) (#1259) 
ccstruct/seam.cpp:66:26: warning:
 array subscript has type 'char' [-Wchar-subscripts]

Fix it by using an unsigned index and use the same type for related values.

fixed missing include for std::back_inserter. 
with Visual Studio 2015 RTM:

Error C2039: 'back_inserter': is not a member of 'std'
Error C3861: 'back_inserter': identifier not found

need "iterator" with Visual Studio 2015 (vc14).

#include <iterator>

ebbfc3ae8d Improve robustness of function LoadDataFromFile (#1207) 
ftell returns a long value which can be negative when an error occurred.
It returns LONG_MAX for directories.

Both cases were not handled by the old code.

f3c4b894dc Fix help message for unicharset_extractor (#1206) 
If unicharset_extractor was called without any argument,
a help message was printed by tesseract::ParseCommandLineFlags.

Replace that by the local help message which is better.

aa6eb6bd46 Remove Tesseract parameter "include_page_breaks" and use FF by default 
Now Tesseract adds a page break (normally form feed) by default.

It is still possible to suppress page breaks by setting an empty
page_separator.
