Why is GREP_OPTIONS deprecated?
The main reason is that it breaks shell scripts. Scripts generally
expect 'grep' to behave as specified in POSIX and as implemented via
traditional 'grep' implementations. GREP_OPTIONS breaks this.
Some shell scripts work around the problem by explicitly unsetting
GREP_OPTIONS before they call 'grep'. However, most scripts don't, I
expect because their authors are not generally aware of this
compatibility issue. So in practice the convenience of GREP_OPTIONS can
be more trouble than it's worth.
* Strategy 4: Write a simple wrapper script. No, I think this is too
dirty and makes more trouble than it solves.
Why is it dirty? What trouble does it cause, other than the trouble
GREP_OPTIONS causes?
