  Does this then constitute a bug in the package-checking code?
  
  With a just-updated R-devel, for a test case I get:

The Title field should be in title case, current version then in title case:
‘Support Functions and Data for "Ecological Models and Data" plus 'optim()'’
‘Support Functions and Data for "Ecological Models and Data" Plus 'Optim()'’

(while I'm nit-picking, I will say that the first time I got a version
of this error a few weeks ago, it took me two or three tries to parse
what "..., current version then in title case" meant.  It is perfectly
correct, I just found it really hard to understand ...)
