Hi,

I use git to manage bdf font files. It it quite cryptic so textconv
for diff output makes it much easier to keep track of changes. The
only problem is that "git add -p" does not seems to use textconv, so I
have to run in parallel "git diff" and "git add -p", then add chunks
accordingly. Can somebody add textconv support to "git add -p" please?
I'm not so good at Perl to do the job.

I don't think this is possible: textconv filters are meant to produce
easily readable output from diff, but in no way are they required to be
injective mappings. So, textconv output cannot to be used in order to
specify a patch uniquely.

The appropriate approach is to use smudge/clean filters. They are
mutually inverse. And, in fact, I just checked: add -p uses the cleaned
version. So, if clean converts to "something textual" which gives you
readable diffs and meaningful stats (and smudge converts to binary bdf)
then that is the way to go.

Right, I did not notice because mine was line by line translation.
I'll convert it to clean filter. Thanks.
