Subject: preserve const-ness when calling strrchr()
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=HEAD;p=thirdparty%2Fcollectd.git

preserve const-ness when calling strrchr()

strrchr() preserves the const-ness of the argument, the argument is a const char*
so the return value should also be a const.
