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.
