Not so in 1.6.2:
> a <- paste(rep("a", 124), collapse="")

[1]

You might at least have checked the NEWS file for 1.6.2:
o system(intern=TRUE) has an undocumented line length limit of
119 chars both on Unix and Windows. The limit is now 8096 and
documented. On Unix (only) every 120th character used to be
discarded.
