[Gdal-dev] preferred diff format

[Brian Claywell]

What's the preferred diff format for submitting patches? For example,
I'm currently using context diffs with three lines of context, e.g.,

diff -rc3 /usr/src/gdal-1.4.0/frmts/hfa/ frmts/hfa/ > hfa-no-data.patch

Are unified diffs preferable? I'm pretty new to submitting patches to
large projects.

Thanks!
