As for any portability issue, you can't simply remove the "-e" just
because it works better for you. Least you should do by submitting such
a patch is telling us your OS and shell name and version; in order to be
sure whether to apply this patch or not is to investigate which shell
flavours and versions support or not -e flag, and in which cases -e is
needed, by reading their respective documentations. FWIW it is
supported and needed on my system (Fedora 12, bash-4.0.35,
coreutils-7.6-8 which provides /bin/echo).
That said, the simplest way to fix this portability issue is putting
"@echo" at the beginning of each line.
Best,
John
