When removing a module during gnulib-tool --update, the sed script to remove files from the test subdir is treating the t as a sed label, rather than as part of the file name to be operated on:
Removing file tests/test-strsignal.c (backup in tests/test-strsignal.c~) Updating file lib/stdint.in.h (backup in lib/stdint.in.h~) Updating file m4/printf.m4 (backup in m4/printf.m4~) Updating lib/Makefile.am (backup in lib/Makefile.am~) Updating m4/gnulib-comp.m4 (backup in m4/gnulib-comp.m4~) Updating tests/Makefile.am (backup in tests/Makefile.am~) Updating ./tests/.gitignore (backup in ./tests/.gitignore~) sed: can't find label for jump to `est-strsignal.c/d' Finished. -- Eric Blake
