Subject: scripts/getver.sh: improve revision output
X-Git-Tag: v17.01.0-rc1~2122
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=15b88df87f28faf4b37c8490c8e3af3fe1e4c0cb

scripts/getver.sh: improve revision output

Change the revision output to r<upstream-revision>+<local commits> so
it is easier to get the base revision (and see if there are local
commits).

Example:
$ ./scripts/getver.sh
r794+3
$
