commit be52f329b68e5427c25247d0d97d8dfef79e7820
Author: Andy Wingo <address@hidden>
Date:   Mon May 7 20:18:56 2012 +0200

    add support for texinfo parsed arguments, like @acronym
    
    * module/texinfo.scm (texi-command-specs): Add a new kind of texinfo
      command, inline-text-args, a sort of a cross between inline-args,
      which are unparsed, and inline-text, which is.  Perhaps this should
      supersede inline-args at some point.  In any case, add acronym as an
      inline-text-args element.
      (inline-content?, arguments->attlist, complete-start-command)
      (parse-inline-text-args, make-dom-parser): Adapt for
      inline-text-args.
    
    * module/texinfo/serialize.scm (inline-text-args): Add serialization for
      @acronym.
    
    * test-suite/tests/texinfo.test ("test-texinfo->stexinfo"): Add some
      tests.

commit 4cec6c221aef72825a05963c95eb633af9a43fcf
Author: Andy Wingo <address@hidden>
Date:   Wed May 2 12:59:11 2012 +0200

    Add a missing SYNC_ALL in variable-ref
    
    * libguile/vm-i-system.c (variable-ref): Add a missing SYNC_ALL.
