On the flip side, it might be useful to some to have the option to set
the value to "fixed" for the "--fixed-strings" argument, in which case
the option becomes less a type of extended regexp and more of a simple
search string. Were that to be the case, I think "grep.patternType"
would feel the most precise.

I think for completeness at the very least I should work in the
"fixed" value as an valid value, option naming aside.
