I don't see a need for hfy-which-etags to go via the shell at all,
so a better change to me would be to use call-process instead of
shell-command-to-string there. I see there's also hfy-shell-file-name
for some reason.

Good point, here's another patch. 

Unless there are further comments, I'll push this patch to master in a few days.
