I was led to this bug report from

  http://lists.gnu.org/archive/html/bug-gnulib/2013-01/msg00058.html.

Could you please re-iterate why @sc and @acronym should be avoided, or
point to a discussion where those reasons are spelled out?  At least
the latest Texinfo documentation (from the 4.13.93 pretest) says
nothing about that; if avoiding these is an official GNU guideline,
IMO the Texinfo manual should mention that, and tell why.

E.g., why @sc{gnu} or @sc{posix} or @acronym{ASCII} are bad?

TIA
