documentation string for caller builtin

[Ernest Adrogué]

Hello,

The documentation string for the 'caller' builtin command in bash.pot
appears to be incomplete, in particular the last 4 lines from the
snippet below which were present in previous versions are now missing:

> caller: caller [expr]
>     Return the context of the current subroutine call.
>     
>     Without EXPR, returns "$line $filename".  With EXPR, returns
>     "$line $subroutine $filename"; this extra information can be used to
>     provide a stack trace.
>     
>     The value of EXPR indicates how many call frames to go back before the
>     current one; the top frame is frame 0.
>     
>     Exit Status:
>     Returns 0 unless the shell is not executing a shell function or EXPR
>     is invalid.

Is this a bug?

Cheers.
