Author: mav Date: Tue Jun 25 17:00:53 2019 New Revision: 349376 URL: https://svnweb.freebsd.org/changeset/base/349376 Log: Fix strsep_quote() on strings without quotes. For strings without quotes and escapes dstptr and srcptr are equal, so zeroing *dstptr before checking *srcptr is not a good idea. In practice it means that in -maproot=65534:65533 everything after the colon is lost. The problem was there since r293305, but before r346976 it was covered by improper strsep_quote() usage.
