Comment on build and INSTALL

Greetings,
   I have noticed two possible small glitches with build and INSTALL.
First, when I run R CMD build latticeDensity, I get the following message:

                  *excluding invalid files from 'latticeDensity'
                  Subdirectory R contains invalid file names:
                       R

However, all the files end up in the zip file (or tar) just fine, and
neither INSTALL nor check seems to care.

The other small glitch is that if you have unmatched brackets in a man file,

INSTALL will flag an error and point out that there are unmatched brackets,
but will often indicate that the unmatched bracket occurs in  a different
file
that is in perfect shape.
