It ignores the quotes a lot of the time. They are less explicit than you may imagine.

yup, "11..22" still finds all numbers from 11 to 22.

But '11..22' yields 11,22 11:22 11/22 etc.

Seems the Unix Bourne shell is seeping in - single quotes are for real, double quotes allow param substitution ...
