Of course I meant the indent's feature.

According to
http://www.mit.edu/afs.new/net/dev/dev/system/sun4m_412/rsp.01/usr/share/man/man1/indent.1
.B /usr/share/lib/tmac/tmac.indent
troff macro package for 
.RB ` "indent \-troff" '

But the file is missing from a Solaris 5.10 where I happen to have an
account. From what I can see, tmac.indent was never added to 4.3BSD or
FreeBSD. Internet search results suggest that Sun OS might be the only
OS to have the file.
