It is often useful to copy
temporary output to generate new script lines. Yes, as asked, it is a cygwin
issue, but if the user is using octave inside cygwin and that impacts the user
interface to octave it becomes an octave issue. Not everyone has the choice of
what operating system to use. Many work environment foist windows upon
unsuspecting users and then expect them to do scientific processing. Many windows
users have little understanding of how Linux, or similar interfaces work. These
interfaces define the underlying way that users interface Octave. I think it is
appropriate to help these users to make their Octave experience a positive one.
Everyone is initially a helpless user and we don't know who will end up being
major project contributors. Finally, sometimes we need to focus less on whether
the venue is appropriate and more on being civil human beings willing to
provide others assistance when they need it.
Again, this is a cygwin issue and not an octave one.
If I remember correctly, after highlighting, hitting "enter" or
"ctrl-c" (I can't remember which one) will copy to the clipboard.
