Not so.

#: builtins.c:369
msgid ""
"Return the context of the current subroutine call.\n"
"    \n"

"    is invalid."
msgstr ""

The other one is present if the caller builtin is compiled as a loadable
builtin, which it is not in the distributed version of bash. I suppose I
could make the two identical, but the loadable builtin version is never
used, so it doesn't seem like a priority.
