Subject: console: report detach message on demand
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9493cb92d82b09d1be4919884944ff91aff0122f;p=thirdparty%2Flxc.git

console: report detach message on demand

When users pass -1 there's there won't be an escape sequence to exit the
console so no need to print a misleading info message about how to detach.
