Yes, that's the traditional UNIX approach.
But I think tehy were different binaries for quite a long time, then links
for a short time.

The current approach is required of GNU coding standards, though it generates
some protests.

That would slow down the wrapper.  I suggest that you add the full path to
the scripts.

But the best solution is probably to move to "grep -E" and "grep -F" --
these are standardized by POSIX, while egrep and fgrep commands are not.
