See ?as.character (which paste effectively calls on non-character objects,
as ?paste says):
Note:
'as.character' truncates components of language objects to 500
characters (was about 70 before 1.3.1).
so it is working as documented. Not then a bug.
You can (and probably should) use a construct like that in terms.formula:
else paste(deparse(form[[2]]), collapse = "")
to convert a formula to a complete character string.
