That's exactly the bogus excuse I expect to get to dismiss my bug 
report, thanks.

That is however bulls**t. The computer is our slave, not the other way 
around. Doing exactly what nobody in their right mind would expect is 
not being helpful, no matter how "logical" it is.

All I want is an error that says "you probably wanted to use 
--modversion". If other gnu software acts like you say (gcc does not) 
they should be fixed to complain about the unnecessary extra arguments.

Of course I used --help and the man page, or I would not have gotten as 
far as trying --version. The help and man page mention "modversion" 
exactly once. They then use the word "version" and "VERSION" about 1000 
times. It also does not help that about 2/3 of the time they use the 
word "package" and only about 1/3 of the time they use the word 
"module". Technically you are correct but there is not a chance in hell 
that anybody will read and remember it correctly. It is just like the 
Emacs help, which is like playing zork, in that technically you have 
everything you need but only if you read and memorized every help 
message you saw since you started the program.
