Problem below with PCRE grep in R-devel; works fine in R-patched. (Unless
there's been an absolutely massive change in rules for updated PCRE version
8.13; jeez I hope not)
> grep( '[.][.]', '', perl=TRUE)
Error in grep("[.][.]", "", perl = TRUE) :
invalid regular expression '[.][.]'
In addition: Warning message:
In grep("[.][.]", "", perl = TRUE) : PCRE pattern compilation error
'POSIX collating elements are not supported'
at '[.][.]'

NB I'm sending to R-devel rather than posting a bug report because (i) I have a
dim recollection that's what we're supposed to do for bugs in R-devel, and (ii)
Bugzilla doesn't include an R-devel version and (iii) couldn't find any
guidance on these matters.
