Subject: Add option "--stats" to test program kvtest. Specifying --stats causes kvtest
X-Git-Tag: version-3.17.0~93
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=befcd8ad84f843cf384d754a8fd203b1945acb59;p=thirdparty%2Fsqlite.git

Add option "--stats" to test program kvtest. Specifying --stats causes kvtest
to output information similar to the shell tool option of the same name.
