Subject: Make win variable internal to x.c
X-Git-Url: https://git.danieliu.xyz/?a=commitdiff_plain;h=323d38da20c8a1d295ab1dbc0fc7ce947ef824e1;p=st.git

Make win variable internal to x.c

There was only a single reference to the `win` variable in st.c, so
exporting that to x.c allows us to rid ourselves of another extern.
