Subject: bpo-38361: syslog: fixed making default "ident" from sys.argv[0] (GH-16557)
X-Git-Tag: v3.9.0a3~71

bpo-38361: syslog: fixed making default "ident" from sys.argv[0] (GH-16557)



The default value of "ident" parameter should be sys.argv[0] with leading path
components stripped, but it contained the last slash, i.e. '/program' instead
of 'program'.
