My ob-elvish module has been working well for me, but I was thinking if the 
best would be to make ob-shell work with elvish instead of having a whole 
separate library for it. I tried adding “elvish” to org-babel-shell-names, and 
it seems to get recognized OK as a shell name, but execution of code blocks 
fails. I get an empty RESULTS block and the following messages:

executing Elvish code block...
Error reading results: (beginning-of-buffer)
Code block produced no output.

This happens even for really simple blocks, e.g.:

#+begin_src elvish
echo "hi"

Before I go looking in the code, I was wondering if anyone can tell if I’m 
missing anything obvious - I just added “elvish” to org-babel-shell-names. 
Since “fish” works fine, I assume a POSIX shell is not expected, but maybe 
there is something else that ob-shell is assuming?
