hgrc: clean up machine-specific settings handling HGRCPATH ends up overriding machine-wide settings, which isn't what I want. Recent hg is nice enough to silently ignore includes of nonexistent files, so just use %include now.

fpath=(~/.zfun $fpath)
autoload -U ~/.zfun/*(:t)

function af_reloadfuncs()
{
  local f
  f=(~/.zfun/*(.))
  for comp in $f ; do
    unfunction $f:t 2> /dev/null
    autoload -U $f:t
  done
}
