Re: [PATCH 1/3] update_unicode.sh: update the uniset repo if it exists

The typical instructions I have seen are a sequence of shell commands

I find this error-prone, as you you may loose the last character while
moving the mouse, or don't check the error message or return codes.
Having a pre-baked shell script, which does use "&&" is in that way
more attractive,
and the README can be as simple as run "update-unicode.sh" and that's it.

That's OK as well.

"contrib/uniwidth/" may be different to find, how about contrib/update-unicode ?

This, too.  And as long as .gitignore pattern is set up correctly
there, I do not think we terribly mind "git clone ..from..there.."
into it, either.
