Nobody knows... Fine.

From TODO list:

Its better to complete remove this stupid feature.
This feature is a kind of AI and will NEVER be smart enough.
As a programmer (grep is often used in shell script) I know better
whether my input is text or binary. If it binary, it's my problem.
For interactive usage it is always better to implement super-AI-grep as
a separate executable and make
'alias grep=super-AI-grep' individually JIMO.

If GNU regex is really faster than NetBSD's, make it a part
of NetBSD base system and link grep with it
until libc's regexec/regcomp is optimized.
