Could be a line abouve line 26 causing the problem. It is just spitting out the errors when it gets to line 26.

Comment out lines 26 & 27, are you still getting errors?

Please change
"Cmnd_Alias restart=/sbin/shutdown -r 0"
to
"Cmnd_Alias RESTART=/sbin/shutdown -r 0"

Cmnd_Alias variable should be uppercase letter, so the correct syntax is Cmnd_Alias RESTART=/sbin/shutdown -r 0

here is the snip from man page of sudoers
Each alias definition is of the form

Alias_Type NAME = item1, item2, ...

where Alias_Type is one of User_Alias, Runas_Alias, Host_Alias, or Cmnd_Alias. A NAME is a string of uppercase letters, numbers, and underscore characters (â _â ). A NAME must start with an uppercase letter. It is possible to put several alias definitions of the same type on a single line, joined by a colon (â :â ). E.g.,

Alias_Type NAME = item1, item2, item3 : NAME = item4, item5

for more information check man sudoers
