The expansion of `~` is something which the shell does when invoking a
command, but if the command is getting a value from a configuration file
then it needs to be supported on a per-app basis, because then the shell
isn't involved doing some of the work for it.

Similarly, if you have something which wants to use `~` as the default
value for a flag, then that's going to be ... "iffy".

So grep for '~' in your config files and try replacing it with $HOME
instead, see if the command does env-var expansion or if you end up with
a directory named '$HOME' in your home-dir.  :^)

There's nothing zsh-specific or zsh-involved here: the problem is
arising _because the shell is not being involved_.
