v1.9.13p3
Add explicit include of unistd.h for getopt(3) and related variables.
Handle "locale -a" returning both C.UTF-8 and C.utf8. It is possible to have mutiple matches from the output of "locale -a". Just take the first one. Fixes GitHub issue #241.
Add eventlog_mail() to send a log message via mail. This is used by mail_parse_errors() to send multi-line messages. Previously, the newlines would be escaped as control characters.
Move eventlog config code into eventlog_conf.c
eventlog_free: free signal_name too
Make sudo pass -Wwrite-strings
