Note quickly written untested code (but compiles!), just to show an idea...
This implements (i hope) curl(1) --stderr option in notmuch(1):
--stderr <file>
Redirect all writes to stderr to the specified file instead. If
the file name is a plain '-', it is instead written to stdout.
This would be useful in emacs interface.
Please comment; I'll do help and manual page changes (and NEWS) if
this is good idea :D
