\sliste has more space than < > arg-st.tex

[stefan11]

If I set some lists with \sliste and have others with < > this looks strange, since < > has no space inserted after the bracket and \sliste has the space that is coming from the argument.

I guess both commands should have half a space or so.

\avm{
[\type*{passive-verb}
% the !! are needed since otherwise the [] inside of sliste are bigger
 arg-st  &  \1 ( \+ !\sliste{ PP[\type{by}]$_i$ }! ) \\
 lex-dtr & [\type*{stem}
            head   & verb\\
            arg-st & < NP$_i$ > \+ \1 < NP, \ldots > ]]  
}
