Previously the query string for piping a message to a command was
"Pipe message to command: " regardless of whether the function was
called with a prefix argument (which pipes all open messages to the
command). This patch modifies the `interactive' command to reflect
this.
---
It has irritated me for a while that I couldn't tell if I had
remembered to press c-u before piping messages to git am etc. This
fixes that. There may be other better ways: suggestions welcome!

Best wishes

Mark
