lyx_mirror/src/BufferView.C
Georg Baum 979fdf7456 Fix strange bibtex problem by converting some more functions to use FileName 
instead of std::string

	* src/support/lyxlib.h
	* src/support/getcwd.C
	(getcwd): return a FileName, not a std::string in filesystem encoding

	* src/support/filetools.[Ch]
	(makeAbsPath): return a FileName, not a std::string in undefined encoding

	* src/support/lyxlib.h
	* src/support/tempName.C
	(makeAbsPath): return a FileName, not a std::string in undefined encoding

	* many other files: Adjust to the changes above
