better just to trim the trailing white space in the Fair enough. Thanks much for dealing with it. Quite frustrating. While I was at it, I configured srclist.txt to strip trailing white space from texinfo.tex too, as I recall that being an issue in the past texinfo.tex has always had, and still does have, trailing whitespace. Thus presumably the exception was installed in the gnulib, automake, ..., whatever hooks. --thanks, karl.
