Removing the macro is bad because pkgsrc does check so many *-config 
files and I wanted to avoid modifying binaries with sed.  I knew when I 
wrote the current _SUBST_IS_TEXT_FILE macro that it was quite lame, and 
I was hoping someone would find a better way.  It sounds like you have a 
better one above, which you should probably commit after the freeze is over.
