Last line is not read from postgres.conf

To reproduce:

1. Add the following line as last line to postgres.conf file

archive_command='copy "%p" "xxxxx"'

Make sure that there is no CR LF characters after this line

2. Restart postgres

3. Issue SHOW archive_command

Observed result:

unset

Note. Adding a newline after this line causes archive_command to be set
correctly.
