These bugs are both fixed now in R-devel and R-patched.

A little bit more advice on the question of "should there be a bug 
report or not":

  -  See the discussion in ?bug.report about "When is there a bug?" 
Both of Henrik's reports were clearly bugs.

  -  Some things are so minor that using the bug reporting system wastes 
time.  My own rule is that if a NEWS entry is warranted, then it is 
helpful to have more depth in the discussion in the bug list.  (The HTML 
version of the NEWS file has hyperlinks into the bug list.)  So spelling 
mistakes should be reported to R-devel, not to the bug system.

  - If you report to R-devel, there's a non-zero chance that your report 
will be missed.  If you submit a bug report, it may not be acted on, but 
it will not be so easily lost.

  - If you're asking for an improvement or suggesting a change, you 
should almost certainly start in R-devel, not in the bug list.  People 
might disagree about the value of your suggestion.  If there's general 
agreement, you can post it as a bug report with "Wishlist" in the 
subject heading.

  - If you do post something as a bug report, it may be helpful to 
include a suggested patch.  This should be against the R-devel source, 
not against a displayed version of a function or a help page.  Identify 
the revision number as well.  ("svn diff" on an R source checkout 
produces a nice patch file, including revision number.)  Don't fix more 
than one thing in a single patch file.  Do explain what your patch does.

  - Don't expect all bug reports to get action.  Sometimes they just 
look like too much trouble to track down and will sit in the bug list 
for a long time, sometimes whoever deals with it will disagree that the 
change is desirable, and will mark it as WONTFIX.
