Hi Pekka,

Thanks.

Jonas,

I've overhauled the manpage write-up to try to incorporate your
suggestions. I wasn't clear about how to interpret a couple of the
things you wrote, but I think your main thrust was to remove
wordiness, get rid of redundancy, and always call attention to the
compatibility notes. I've tried that, mostly be re-ordering things so
that the natural flow of the documentation on parameter interpretation
that was in-place before my change now survives. Now it just reads
like:

- *name* gives the socket to use (it's default value is wayland-0)
- $WAYLAND_DISPLAY replaces the default
- both *name* and $WAYLAND_DISPLAY are allowed to be absolute paths
- implication: if $WAYLAND_DISPLAY is absolute, then the connection
attempt will be too
- $WAYLAND_SOCKET overrides all of this, if it's set
