I guess this is surprising because with a POSIX grep(1), if I read the
description correctly:
1) If the * is the very character of a BRE (since POSIX has BRE and ERE)
it shall be treated as is---but the remaining of the expression is
interpreted.
2) In a ERE, if the * is the very first character, or follows |,
^ or ( this is undefined.
But I must admit that I was unaware, till Erik's message, of both the
Plan9 behavior, and even the "details" of the POSIX behavior...
