 I noticed this in my build logs from fate runs:
 {{{
 .../tests/fate.sh: line 90: /bin/cat: Argument list too long
 }}}

 It looks benign because the error should be handled here:
 {{{
     cat ${build}/tests/data/fate/*.rep >>report || for i in
 ${build}/tests/data/fate/*.rep ; do cat "$i" >>report ; done
 }}}

 Please add a 2> /dev/null in there, so this doesn't log an error message
 to stderr.
