Handling getopt for option without optional argument value

[lisa-asket]

Good Evening Chet,



An maintainer of bash, I want to suggest an improvement to the capability of 
bash built-in

getopt to also handle long options, or another implementation with a different 
name if

you are worried that the changes could break people's scripts.



libc does have the long option function, whilst bash is the most widely used 
shell packaged
by default for most distributions, making the use of long options in bash 
functions

extremely useful. Many things that can be done in Gnu can be done via command 
line. 



I have many tools available on the command line that I use everyday.

To be fair, you don't know their full requirements. It's all about fitting
the tool to your requirements.
