Yes.

How about just applying the following into make_etags?
+if [ $# -gt 1 ] || ( [ $# -eq 1 ] && [ $1 != "-n" ] )
+then echo "Usage: $0 [-n]"
+ exit 1
+fi

Thanks for updating the patch!
With the patch, make_etags caused the following error messages
on my MacOS.
$ ./src/tools/make_etags
No such file or directory
No such file or directory
To fix this error, probaby we should get rid of double-quotes
from "$FLAGS" "$IGNORE_IDENTIFIES" in the following command.
- xargs ctags $MODE -a -f $TAGS_FILE "$FLAGS" "$IGNORE_IDENTIFIES"
+ xargs $PROG $MODE $TAGS_OPT $TAGS_FILE "$FLAGS" "$IGNORE_IDENTIFIES"
+ else ctags --help 2>&1 | grep -- -e >/dev/null
+ # Note that "ctags --help" does not always work. Even certain ctags does not have the option.
This code seems to assume that there is non-Exuberant ctags
supporting -e option. But does such ctags really exist?
I fixed the above issues and refactored the code.
Attached is the updated version of the patch. Thought?
