Tweaked the increment style of a "for" loop.

[rsync/rsync-patches.git] / acls.diff

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

    patch -p1 <patches/acls.diff
    ./prepare-source
    ./configure --enable-acl-support
    make

See the --acls (-A) option in the revised man page for a note on using this
latest ACL-enabling patch to send files to an older ACL-enabled rsync.
