Ahah!  Agreed, and fixed in master (I'll push as soon as the testsuite
finishes); thanks for persevering with me.  While the change to ltdl.mk was
indeed cosmetic, I didn't account for the fact that during generation of
libltdl/Makefile.am multiple libltdl/libltdl on a single line of the source
file breaks the edit process.

Thanks again for your help in tracking down and fixing that bug.

Cheers,
