It took me a while, but I finally managed to reproduce this one.  Here's the 
formula I finally got to work:

reset gnulib to current gnulib.git
reset m4 branch-1.6 to current m4.git
gnulib-tool --update
reset gnulib to f74d4, then apply patch to gnulib-tool
reset m4 branch-1.6 to eeddcc^
gnulib-tool --update

at which point, ignore-removed contains:
test-freadptr.c
test-freadptr.sh
test-freadptr2.c
test-freadptr2.sh
test-freadseek.c
test-freadseek.sh
test-memchr2.c

and sed-ignore-removed contains:
/^test-freadptr.c/d
/^test-freadptr.sh/d
/^test-freadptr2.c/d
/^test-freadptr2.sh/d
/^test-freadseek.c/d
/^test-freadseek.sh/d
/^test-memchr2.c/d
/^/test-freadptr.c/d
/^/test-freadptr.sh/d
/^/test-freadptr2.c/d
/^/test-freadptr2.sh/d
/^/test-freadseek.c/d
/^/test-freadseek.sh/d
/^/test-memchr2.c/d

Hmm.  Duplicated lines in sed-ignore-removed, with the second half treated as 
matching the expression /^/ and performing the t operation to the label est-
freadptr.c/d.  Hope that helps; I haven't looked closely into what gnulib-tool 
is doing at this point.
