o gsub(perl=TRUE) returned a string which printed with trailing
garbage if there was a match at the beginning whose
replacement was shorter. (PR#7479)The crucial comment is that it only happened for a match at the beginning, and sub() was using the same code.
Pre-compiled versions of R-patched for Windows XP are available on CRAN.

I have a problem doing substitution using sub and perl=TRUE when the elements of x have fewer characters than the replacement string. Let me show you what I mean:
sub("m","billy","m")[1] "billy"
But using perl=TRUE, I can only return a result as long as my x:sub("m","billy","m",perl=TRUE)[1] "b"
sub("m","billy","ma",perl=TRUE)[1] "bi"
Etc.
Is this supposed to happen like this? I couldn't see a mention of this requirement in the help.
I am using R 2.0.1 on windows xp.
