Subject: [PATCH] Fix troff warning

.eo/.ec sections seemingly need explicit empty lines using .sp

troff:<standard input>:535: warning: expected numeric expression, got '\'
troff:<standard input>:538: warning: expected numeric expression, got '\'
troff:<standard input>:541: warning: expected numeric expression, got '\'
