# Prompt with mesg, return non-zero on q. Also allows setting -x and +x,
# shell escapes and the passing of default values

# Usage: prompt "message" [default]
# Argument is a quoted message
# Dependencies: expr
# Notes: returns 1 if the user answers q or Q, returns 0 otherwise
#        if $quit is not set, it is set to "quit"
#        $cmd is set to whatever is input by the user, and then can
#               subsequently be used in the shell script.
