The functions prefixed with _ are completion functions. The files for the
functions themselves are located elsewhere. To find one you can either run
`whence -v` on it (but it must be loaded first), or do something like the
following:

  # Print matching file paths
  print -rl - $^fpath/**/run-help(N)

  # Print contents of matching files
  cat -- $^fpath/**/run-help(N)

(whence/which/where can also print the contents, but again only after the
function is loaded, and they will strip all of the comments and formatting)
