Changes by: Eric S. Raymond <esr> 07/02/07 12:18:52
Modified files:
man : groff_out.man
Log message:
First step in macro simplification; eliminate list1..n, simplify
.offset and .index_offset so they no longer require groff-specific
features or eqn (instead, use troff micromotions for subscripting).
