in repository groff.
commit 9165d7d228141816e6046d5cad17be6f8d60ff73
Author: G. Branden Robinson <[email protected]>
AuthorDate: Sat Jan 17 11:10:30 2026 -0600
doc/groff.texi.in: Fix Savannah #67838 (1/2).
Stop attempting to manually recapitulate the topology of the Info node
tree with arguments after the first to `@node` commands; doing so is no
longer required by recent versions of Texinfo--thanks to Alexis
Hildebrandt for bringing this to my attention and providing a
proof-of-concept patch--but the normative topology of the directed tree
is radically unintuitive to me, leading me to make many errors. It
_seems_ like Info's idea of the node traversal strategy preferred by
humans is breadth-first in one direction ("Next") and _depth_-first in
the other ("Prev").
