rGf77b5b295da3: Allow -DNO_STRICT_REGEX to restore historic regex behavior
Summary

Allow restoring the behavior of '{' as described in regex(3).
Ie. only treat it as start of bounds if followed by a digit.

If NO_STRICT_ERE is not defined, the behavior introduced by
commit a4a801688c909ef39cbcbc3488bc4fdbabd69d66 is retained,
otherwise the previous behavior is restored.

It occurs to me that this is the BRE path, but it'd be good for the knob to be consistent across BREs and EREs- maybe just rename the knob to NO_STRICT_REGEX? I don't think I have any complaints otherwise.
