shirr definitions

[David Randall]

Melissa, Fran, and Linda all submitted choices having to do with alternate
definitions of shirr, and, for some of them, conceivably a related version
of the definition.  I was very busy and didn't even look at anybody's
messages till tonight; I apologize to all three of you.  Rather than waste
time, I'd like to go ahead with the definitions I got.  Perhaps if the
result is a tie, one of you can arbitrarily be chosen to do the next word?
We'll see.  1 point choice only, please.--David
