[Bug 3381] RekeyLimit mechanism does not work if it is defined at the end of the file

--- Comment #3 from yanger <yaniv.german at gmail.com> ---
I have only commented lines in my configuration except the last one.
Adding an example. 
The numbers are just an example. 
on DEBUG3 I can see messages that tries to set the Rekey to the values
at the end of the file  - but when I am looking for the actual Rekey
messages   I don't see them

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/local/bin:/usr/bin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.

# If you want to change the port on a SELinux system, you have to tell
# SELinux about this change.
