Patch files is attached.  There have not yet been any tagged 
releases in the source repo, so I have left the version as 0.

I initially tried using a patch file instead of manually using the 
substitute snippet, but that was failing with an error that 
vterm.el was read-only.  If there is a workaround, I would gladly 
return to using a patch file.
