[Rd] bug in read.table (PR#2764)

[Man, Michael]

Professor Ripley,

Thanks for your help.  The file was indeed generated on MacOS, which was
unknown to me till I checked with the sender.

Without the file, how can we do anything about this?  My guess is that
this is a MacOS file, in which case the problem is PR#2469 which is long
solved.  Please try R-patched or a beta of R-1.7.0.

BUG FIXES

    o   The fix to PR#2396 broke read.table() on files with CR line
        endings. (PR#2469) Separate problem with this on Carbon Mac
        build fixed as well.

The other workaround is to use files in the native file format ....


BTW, `_' is deprecated, so please don't use it in postings, especially in 
the unreadable way shown here.
