Subject: tools/kvm_stat: sort '-f help' output
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=aa12f594f97efe50223611dbd13ecca4e8dafee6;p=openwrt%2Fstaging%2Fblogic.git

tools/kvm_stat: sort '-f help' output

Sort the fields returned by specifying '-f help' on the command line.
While at it, simplify the code a bit, indent the output and eliminate an
extra blank line at the beginning.
