"blame -c" should be compatible with "annotate"

There is no reason to have a separate variable cmd_is_annotate;
OUTPUT_ANNOTATE_COMPAT option is supposed to produce the compatibility
output, and we should produce the same output even when the command was
not invoked as "annotate" but as "blame -c".

Noticed by Pasky.
