[2/6] commit-graph: collapse parameters into flags

Commit Message

John Passaro via GitGitGadget Jan. 23, 2019, 9:59 p.m. UTC

From: Derrick Stolee <[e-mail]>

The write_commit_graph() and write_commit_graph_reachable() methods
currently take two boolean parameters: 'append' and 'report_progress'.
We will soon expand the possible options to send to these methods, so
instead of complicating the parameter list, first simplify it.

Collapse these parameters into a 'flags' parameter, and adjust the
callers to provide flags as necessary.
