Ah, good to know that it is already reported.

To be fair, tex.web does not *require* this to be the "real" file  
name, although it encourages implementers to do this; see section 525,  
which says that that "the following routine ... should ideally be  
changed to deduce the full name ...". So getting the full name here is  
an implementation-dependent enhancement, but doing so is recommended  
and clearly helpful.

Does it also provide the full path? So if \input foo actually caused  
TeX to read c:/some/path/to/texmf/tex/macros/foo.tex, does the  
name_field get updated only to foo.tex, or to the full path? SyncTeX  
needs the full path, as it cannot reliably know the search paths that  
TeX may have been using.
