[R] Input buffer overflow

[Gabor Grothendieck]

No one answered this question but to answer my own question I did notice
that since I  posted this, there have been changes to parse.Rd in the
development version of R:

  https://svn.r-project.org/R/trunk/src/library/base/man/parse.Rd

indicating:

  "a limit of 8192 bytes on the size of strings which can be parsed."
