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

quoted

Sure, and I'd rather see the update-unicode.sh script moved
somewhere in contrib/ while at it.  Those who are interested in
keeping up with the unicode standard are tiny minority of the
developer population, and most of us would treat the built width
table as the source (after all, that is what we ship).

To be bluntly honest, I'd rather not to see "update-unicode.sh"
download and build uniset at all.  It's as if po/ hierarchy shipping
with its own script to download and build msgmerge--that's madness.
Needless to say, shipping the sources for uniset embedded in our
project tree (either as a snapshot-fork or as a submodule) is even
worse.  Those who want to muck with po/ are expected to have
msgmerge and friends.  Why not expect the same for those who want to
update the unicode width table?

I'd rather see a written instruction telling which snapshot to get
and from where to build and place on their $PATH in the README file,
sitting next to the update-unicode.sh script in contrib/uniwidth/
directory, for those who are interested in building the width table
"from the source", and the update-unicode.sh script to assume that
uniset is available.

OK with the contrib - that's an improvement.
About the instructions how to download and compile:
(we don't need to change the  $PATH, do we ?)
I don't know.
The typical instructions I have seen are a sequence of shell commands
to be executed, which hopefully simply work by doing "copy-and-paste".
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.

uniset is a small project and where should we put it ?
a) inside the Git tree?
b) /tmp ?
c) into the $HOME directory ?
d) /usr/local

a) is quick and dirty
b) probably OK
c) Not sure about tha
d) Needs super user rights
Can we try to find a good place ?

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

OK. So please don't merge bb/unicode-9.0 to next yet; I'll prepare a
reroll following your description.

Torsten, is this alright with you?

sure
