Just in case it hasn't been mentioned before: At least for the `.so'
request, there is a big difference between



  .    so

The former gets preprocessed with `soelim', while the latter is only
recognized by `troff'.  In other words, this difference provides a
means to suppress file inclusion even if `soelim' is used.

Admittedly, this mechanism doesn't make much sense with other
preprocessors in general, but I think it's not a bad idea to stay with
this scheme for orthogonality:


can be handled by a preprocessor, while


is something only `troff' should process.
