Hi,

After binding <return> to a user defined widget, I found that the
execute-named-command and where-is widgets no longer work because like
isearch and menu-select they have hard-coded a check for accept-line.
This patch adds a local keymap for these widgets to use when reading
the command name making it easier to use a user-defined widget in your
main keymap to replace accept-line.

thanks,
Greg
