Handle PCRE2 exception: match limit exceeded

[Morantron]

Originally pointed out here #112 (comment)

It seems to be a PCRE2 exception, although I still don't know under which circumstances it's raised.

@NeilHanlon can you share the contents of the pane that triggered the exception? You mentioned it crashed on empty panes right? I think it could be related to characters in the shell prompt.

• You can open a new pane and figure out the pane id by running echo $TMUX_PANE
• Clear screen in that pane.
• In another shell or pane run tmux capture-pane -J -p -t <value-of-tmux-pane> > /tmp/pane-contents

So, I went to try and reproduce this... and I can't.

I rebooted over the weekend, so, I guess it is possible that has something to do with it.

I've tried now in a few different panes with varied histories, and I can't seem to reproduce it, so, I think it's safe to close this for now.

Sorry for the noise, and thank you for your work on Fingers :)

No prob! Thank you! Let me know if it happens to you again
