[PATCH 4/5] pretty describe: de-const'ify struct commit arg of format_commit_message()

[PATCH 4/5] pretty describe: de-const'ify struct commit arg of format_commit_message()

[René Scharfe]

As a preparation to use describe_commit() in format_commit_message(),
the const attribute of the struct commit parameter must go, as
describe_commit() needs to change the name related members in order
to do its work.

This change requires changes in other places, too -- those that call
format_commit_message() with a const struct commit, and the places
calling those places.
