You're apparently new to Unix at all.

:)
Nope. The quotes are being stripped before the arguments will be
passed to the utility (the name of the utility is unobvioulsy `test'
in this case). Thus
X"NO"
"XNO"
XNO
"X"NO
are all the same. The quotes around XNO aren't strictly necessary at
all, those around the variable (``${namedflags}'' above) will prevent
the shell from splitting the argument into multiple words if the
variable contains ``white space''.
I'm going to close the PR if noone beats me on this.

Never trust an operating system you don't have sources for. ;-)
