jffs2dump: rewrite --help output to be more suitable for help2man
$ help2man /usr/sbin/jffs2dump | man /dev/stdin currently creates badly formatted output like -b --bigendian image is big endian -l --littleendian image is little endian -c --content dump image contents -e fname --endianconvert=fname convert image endianness, output to file fname -r --recalc- This patch modifies the --help output for jffs2dump to be more suitable for help2man and thus makes it possible to easily create manual pages that stay up-to-date.
