The previous patch has added functions that implement per-file contents encoding selection logic. This one modifies core gitk code to use them.
Since diffs usually contain multiple files, which may have different values of the encoding attribute, they are initially read as binary, and encoding conversion is applied to individual lines, based on the active set of diff headers.
As a side job, this patch also fixes some bugs in handling of non-ASCII filenames. Core git apparently supports only locale-encoded filenames, so processing is done using the system encoding.
