get_patch_filename(): split into two functions
The function switched between two operating modes depending on the NULL-ness of its two parameters, as a hacky way to share small part of implementation, sacrificing cleanliness of the API. Implement "fmt_output_subject()" function that takes a subject string and gives the name for the output file, and on top of it, implement "fmt_output_commit()" function that takes a commit and gives the name for the output file.
