XML/Info discrepancy for @deffn CATEGORY

[Thien-Thi Nguyen]

I just noticed in the latest IXIN 1.5 tarball file d/serveez.xml,
generated by makeinfo 4.13.92, that the input line:

 @macro PROC
 Scheme Procedure
 @end macro

 @deffn @PROC{} global-init servertype

shows up as:

 <definitionterm>
   <indexterm index="fn" mergedindex="cp">Procedure</indexterm>
   <defcategory>Scheme</defcategory>
   <deffunction>Procedure</deffunction>
   <defparam>global-init</defparam>
   <defparam>servertype</defparam>
 </definitionterm>

That is, the category is "Procedure" instead of "Scheme Procedure", and
everything else is shifted by one.  I tried to put curly braces in the
macro definition, but that produces an error:

 ./guile-api.texi:567: Misplaced { (possibly involving @PROC)
 ./guile-api.texi:567: Misplaced }

The weird thing is that Info output is fine (including indexing).

Another data point: Curly braces at the "call site":

 @deffn address@hidden global-init servertype

work fine for both Info and XML output.  Also, w/ or w/o curly braces at
the call site work fine for both Info and XML output for makeinfo 4.13
(in IXIN 1.4 d/serveez.xml, for example).

Lastly, i searched NEWS for something that fits this new behavior, but
did not find anything.  Am i missing something?
