there was no leading space macro is stored in register @code{lss}.
Note that @code{lsn} and @code{lss} are available even if no leading
space macro has been set.
+
+The first thing a leading space macro sees is a token. However, some
+escapes like @code{\f} or @code{\m} are handled on the fly (see
+...@ref{gtroff Internals}, for a complete list) without creating a token
+at all. Consider that a line starts with two spaces followed by
+...@code{\fifoo}. While skipping the spaces @code{\fI} is handled too so
+that groff's current font is properly set to @samp{I}, but the leading
+space macro only sees @code{foo}, without the preceding @code{\fI}.
+If the macro should see the font escape you have to `protect' it with
+something which creates a token, for example with @code{\&\fIfoo}.
