I find the UN*X shells' quoting conventions to be quite adequate at
avoiding the need to require a SPACE anywhere.  If you want something which
contains meta characters to become part of a parameter-word, you quote it.
That makes it pretty simple to put together whatever you need.

grep some-text *.c
egrep "some-text|other-text|other-text" *.c

etc.

Of course the biggest part of this is educating people which characters
are special meta-characters which the shell will treat in a special way.

I usually just tell people, when you want a character that is not a
letter or digit to be a part of a parameter to a program, just quote it.
This results in no surprises.
