Should def line @ continuation insert a space?

[Gavin Smith]

This is input showing a def line continuation:

@deffn Function foo (bar,@
baz)
aaaaaaaaaa
@end deffn

This is the output with Texinfo 4.13:

 -- Function: foo (bar, baz)
     aaaaaaaaaa


This is the output with Texinfo 7.0.3:

 -- Function: foo (bar,baz)
     aaaaaaaaaa

In addition, with texinfo.tex, a space is output between "bar," and "baz".

I tried looking back through mailing lists and ChangeLog entries for
any information but there isn't much.  From what I can see, this line
continuation feature was added in December 2003 (entry on 2003-12-13 by
Alper Ersoy), and included in Texinfo 4.7 in April 2004.

Was this perhaps a deliberate change made when texi2any was rewritten
in Perl?
