Subject: [PATCH] install.sh: use `printf` to print post-install instructions

In Fish shell, parentheses are for command substitution, so the
parenthesised subshell used for `echo` grouping does not work there.
Instead let's use `printf` to print the post-install instructions; it's
more portable.

Fixes #880.
