Sorry for the late reply.  It's still not really clear what you want
to achieve.

Please give a (short) source code example which shows what you would
like to have.  Looking at your PDF, I think you want to use the power
of the .dei macro to bypass problems with .eo:

  .de end-macro
  ..
  .ds end-macro-name end-macro\"
  .
  .
  .de begin
  .  ds env-name \\$1\"
  .  ds end-name end\"
  .
  .  eo
  .
  .  dei env-name end-name
  .    eo
  ..
  .
  .
  .de end
  .  ami env-name end-macro-name
  .    ec
  .  end-macro
  .
  .  ec
  .
  .  if !'\\*[env-name]'\\$1' \
  .    ab environment `\\*[env-name]' ended with `\\$1'
  ..
  .
  .
  .
  .begin foo
  This is a \test with
  \n[umbers] and \*[strings].
  .end foo
  .
  .
  .nf
  .foo
  .fi

  This is a \test with
  \n[umbers] and \*[strings].


Result:

  This is a \test with
  \n[umbers] and \*[strings].

  This is a est with 0 and .

Well, this should be straightforward.  You can test whether a macro,
string, diversion, or request `foo' is defined with

  .if d foo

Otherwise, you can handle your fifth parameter as a file.
