[MPIWG Fortran] Question about 388 errata

[Rolf Rabenseifner]

I propose in
https://svn.mpi-forum.org/trac/mpi-forum-web/attachment/ticket/388/errata-30-ticket388-2013-09-12.pdf

Page 7 lines 14-15 read
 
  For TS 29113 quality, new routines 
  are needed only for routines with choice buffer arguments.

but should read

  If the Fortran compiler implements TS 29113, then new routines 
  are needed only for routines with choice buffer arguments.

(We always use the short-cut TS 29113, the long version is in the bib-list)

Jeff S., Jeff H., Craig, Bill L.,
 
    please give an explicit okay (or a better text).

Best regards
Rolf
