Yes, something like this would be very useful for the programable
completion.

But in the meantime can you describe what exactly these options do?

My understanding is this:
nospace: No not append a space after a completion even if it's the only
one.
filenames: Quote shell meta-characters and append a / if the sole
completion is a directory
dirnames: Has no effect if the compspec generates no matches?

So probably at least filenames could be emulated by the completion
function, right?

Description:

scripterror (source below) is a function that 
  puts the argument of option m in variable 'message'
  puts the argument of option M in variable `testText'

but as you can see, if i supply both options, the argument for -M has gone into 
the argument for -m instead:

# -bash 37 > scripterror -m messagetext -M testtext
testItem=
message=testtext
Warning: in -bash: testtext

Also, if I supply only option -M, its argument again gets treated as if it is 
the argument of -m:

# -bash 38 > scripterror -M testtext
testItem=
message=testtext
Warning: in -bash: testtext


Note however that if I only list one of -m or -M in the getopts list, they are 
handled with case sensitivity. (I.e., 
-m can't be used for -M)

Repeat-By:
==

load the function scripterror below, then issue  the test commands above to 
demonstrate the problem.
Look at the value of the variables message and testItem.
