Fixes the following warnings:

rebase-interactive.c: In function ‘edit_todo_list’:
rebase-interactive.c:137:38: warning: zero-length gnu_printf format string [-Wformat-zero-length]
    write_file(rebase_path_dropped(), "");
rebase-interactive.c:144:37: warning: zero-length gnu_printf format string [-Wformat-zero-length]

...
On a tangent: what's wrong with empty format strings?

Those functions that are truly printf-like, such a call would be
no-op and an indication of possible typo ("did you forget a %s or
something?"), I presume.

But many of our functions that take printf-like format strings will
do useful things even when an empty string is given, so the warning
is unwanted.
