Just played with that. Here's the full error:

        augtool> print /augeas//error
        /augeas/files/etc/modules.conf/error = "parse_failed"
        /augeas/files/etc/modules.conf/error/pos = "736"
        /augeas/files/etc/modules.conf/error/line = "16"
        /augeas/files/etc/modules.conf/error/char = "0"
        /augeas/files/etc/modules.conf/error/lens = "/homes/lutter/code/augeas/lenses/modules.aug:55.10-.32:"
        /augeas/files/etc/modules.conf/error/message = "Iterated lens matched less than it should"
        
Line 16 is the first non-comment, the instruction 'keep'.

Looking at the file in Emacs, it has DOS line endings. Running dos2unix
on it fixes the problem - I'd assume that the DOS line endings are an
artifact of downloading the file from a web server, not the way any sane
person would store modules.conf on their Linux machine.
