Since we're doing this, can we also #define printf(...) printf_P(__VA_ARGS__)? It will make it much easier to upgrade umm to upstream version, if we ever want to do that.

Thanks for the collaborator status. I'm happy to help out.
I'll refactor the patch this weekend and put in a new one with printf() macro'd instead of the changes inline.

UMM debugging strings are normally placed in RODATA, which uses up scarse memory. Move them to PROGMEM and use macros to replace printf with a version that can handle ROM strings.

Store the UMM debug format strings in PMEM instead of RODATA. Frees around 300 bytes of RAM with debugging disabled, much more when debugging is enabled.
