  more precisely, angle brackets would represent any "replaceable"
content, regardless of where it occurs.

  same rationale as above, [<...>] would represent both optional *and*
replaceable content. and so on, and so on.

  the only other obvious inconsistency i've seen is, when referring to
an environment variable, i've seen both of:

  `VARIABLE`
  `$VARIABLE`

my personal preference is the one without the $ if just referring to
the variable, without trying to dereference it. but that's just me.
