Prompt tracking breaks in bash when systemd OSC context is enabled

[sharkdad]

There's a new systemd OSC context feature that breaks a lot of existing shell/term software, see systemd/systemd#39114. This feature is enabled on Fedora 44 and causes ghost.el's prompt tracking to fail, C-c M-p/n don't find prompt instances anywhere.

To get it working again I disable the systemd OSC context with these commands:

rm -f /etc/profile.d/80-systemd-osc-context.sh \
    && mkdir -p /etc/tmpfiles.d \
    && ln -sf /dev/null /etc/tmpfiles.d/20-systemd-osc-context.conf

I think the fix might be something about handling PROMPT_COMMAND when it's an array in ghost.el's shell integration but I don't care enough to look further. Just letting you know more folks might run into it as this rolls out.

Thanks for the report.
Should be fixed on latest main.
