ah, that's not at all related to merging, it's just a misuse of a 
formatter: I wrote a format string (probably directed to the internal 
logger) and didn't pass enough arguments to it.

unfortunately boost doesn't give us enough information in the format 
exception to know which string has the error. the easiest way you can 
help narrow this down is within gdb:

 $ gdb --args monotone merge
 ...
 (gdb) break main
  Breakpoint 1 at 0x82f46a9
 (gdb) run
 Starting program: monotone
 ...
 Breakpoint 1, 0x082f46a9 in main ()
 (gdb) catch throw
 Catchpoint 1 (throw)
 (gdb) continue
 Continuing.
 Catchpoint 2 (exception thrown)
 0x0022c146 in __cxa_throw () from /usr/lib/libstdc++.so.5
 (gdb) back
 #0  0x0022c146 in __cxa_throw () from /usr/lib/libstdc++.so.5
 #1  ...
 #2  ...

if you can capture the backtrace there, it will tell me exactly which 
formatter is failing. sorry, it's just a typo on my end, it has no deep 
semantic meaning.
