Fix the instructions on changing plugins install dir
The instructions given here need to be modified after tmux 3.4. The issue mentioned here.
TLDR : path values for options should be given in double quotes instead of single quotes.
The reason you need double-quotes is because you had a variable in your path, $HOME which needed to be interpolated. String interpolation only happens with double-quotes, not single-quotes. Single-quotes is fine if you don't use variables. This could be called out by the docs, but they're not wrong as they are.
IMO while fixing that, it'd be prudent to clarify. '/some/other/path/' is fairly ambiguous. Do you point it to the upper plugins directory or the tpm directory itself? Which is it?
"${HOME}/.config/tmux/plugins/"
"${HOME}/.config/tmux/plugins/tpm"
"${HOME}/.config/tmux/" (admittedly unlikely)
It's understood that you can change it to whatever you want, but a sane example makes sense.
It's also WELL past time to put anything directly in ~/. This should either be in ~/.config/tmux or ~/.local/share/tmux possibly ~/.local/tmux just not ~/.
I agree @HalJordan, unfortunately this repo is fairly unmaintained. I just try to add comments where I can. We're at the stage where a fork would be sensible.
