I think instead of "root directory of DIRECTORY" this should say "the
top-level directory of DIRECTORY's repository".

Our convention is to leave 2 spaces between sentences in comments and
doc strings.

"When called from Lisp" implies that this function can be called in
some other way, which is generally correct only with commands.  But
this function is not a command, so I'm unsure what this means here.
