I said with "-i" vs. without "-i" would make two 2 orders of magnitude
difference. (Unrelated to multibyte vs. singlebyte.)

What are fgrep-FBSD and fgrep-ORIG?

Where is WITH_INTERNAL_NOSPEC documented? src.conf(5) doesn't mention it.

Why isn't WITH_INTERNAL_NOSPEC enabled by default when it accounts for such a
drastic improvement?
