I finally got it to work with this syntax:
left lbrace alignl stack {`left [ +approximant right ]~"___
X"_0~"]"rsub stem # `left [ +nasal right ]~"___ X"_0~"]"rsub stem #
`left [ binom {+syllabic} {+front} right ]~"___ X"_0~"]"rsub stem # `
{"___ " _stem left [ +syllabic right ]} } right rbrace
Note that I changed the offending section from "stack" with the
elements separated by #, to "binom" without the #.
The problem wasn't that I had left out a terminating bracket; it was
that the stack function refused to work in a bracket element nested
inside a brace element. If I took just the bracket element out and used
it as a standalone formula it appeared fine.
Luckily the bracket needed only two items, so I was able to substitute
"binom" for "stack," and that got me home.
I wish I could find a complete reference to the formula commands with
examples. The Help is only a couple of pages. I found a PDF online that
was six pages, but it was written in 2005 and half the features were
not displayed with examples.
