Wouldn't build-aux/rerun be a good candidate for a new gnulib module?
Wrt. portability, this line:
diff -u "$cachefile".old - | sed -e '1,2d' -e
'/^-/{s/^-/-'"$color_blue"'/;s/$/'"$color_off"'/}' -e
'/^+/{s/^+/+'"$color_red"'/;s/$/'"$color_off"'/}'
could profit from a quick test whether diff supports -u, and the sed
script something like
sed -e '1,2d' \
-e '/^-/{' -e 's/^-/-'"$color_blue"'/' -e 's/$/'"$color_off"'/' -e '}' \
-e '/^+/{' -e 's/^+/+'"$color_red"'/' -e 's/$/'"$color_off"'/' -e '}'
then a --version option, and the script would be in pretty good shape
already. Maybe if the exit status could be nonzero if either the diff
is nonempty or the $command failed, that would be neat.
Cheers,
Ralf
