Compiled Sass placing } at end of last line - css

Question

I have only just started using Sass this morning, after reading about it last night. I think I'm understanding it (but feel free to to comment if you disagree). I've ran into one problem though, be it minor but inducing an OCD head ache.
ul#primary-nav {
font: 400 16px $font-stack;
margin: 0 auto;
text-align: center;
li {
display: inline-block;
margin: 0 15px;
&:first-child {
margin-left: 0;
}
&:last-child {
margin-right: 0;
}
}
a {
color: $grey;
padding: 10px 5px 15px 5px;
&:hover {
border-bottom: $blue solid 6px;
.active {
font-weight: 700;
}
}
}
}
This outputs the following code:
ul#primary-nav {
font: 400 16px "Lato", sans-serif;
margin: 0 auto;
text-align: center; }
ul#primary-nav li {
display: inline-block;
margin: 0 15px; }
ul#primary-nav li:first-child {
margin-left: 0; }
ul#primary-nav li:last-child {
margin-right: 0; }
ul#primary-nav li a {
color: #777777;
padding: 10px 5px 15px 5px; }
ul#primary-nav li a:hover {
border-bottom: #25aae1 solid 6px; }
ul#primary-nav li a.active {
border-bottom: #25aae1 solid 6px;
font-weight: 700; }
So the code itself is fine for what I want but I was wondering why it is adding the closing paragraph tag to the last line. Is there a way to force it on the line below
ul#primary-nav li a:hover {
border-bottom: #25aae1 solid 6px;
}
I know it's only a small thing but it would make me ever so happy.

Yes it is entirely possible to satisfy your OCD needs: basically you need to make sure the compiler is outputting in expanded style.
From the docs:
Nested
#main {
color: #fff;
background-color: #000; }
#main p {
width: 10em; }
Expanded
#main {
color: #fff;
background-color: #000;
}
#main p {
width: 10em;
}
From the command do this with sass style.css --style expanded, but your build system might also expose the option somewhere - check its docs.
