Fixed a failing hunk.

[rsync/rsync-patches.git] / omit-dir-changes.diff

This patch from Antti Tapaninen added the --omit-dir-changes option, which
tells rsync to not affect any attributes on the directories in the transfer.

To use this patch, run these commands for a successful build:

    patch -p1 <patches/omit-dir-changes.diff
    ./configure                              (optional if already run)
    make
