[Rd] Font size in Mac OS X console won't stick (PR#7830)

[tim.sears at anu.edu.au]

On Mac OS X, the console keeps changing the font size back to a small 
size after I increase it.

Also hitting "command-shift-+" shrinks the font at first. It only 
increases it after you hit "command-minus" once.

Also the command bug.report doesn't work properly if I copy/paste the 
example from the help file. Maybe it only works on another system...

bug.report(subject = "",
+            ccaddress = Sys.getenv("USER"),
+            method = getOption("mailer"),
+            address = "r-bugs at r-project.org",
+            file = "R.bug.report")
