	Isn’t it already possible with xargs(1)?  Depending on the shell
	in use, it may be possible to, say:

$ etagx () { (cat < .etags ; printf %s\\n "$@") | xargs etags ; } 
$ etagx *.m

	The last ‘*.m’ bit would require duplicating shell’s own
	wildcard expansion in Etags, and it doesn’t seem like an
	outright clever idea to me.
