From: SZEDER Gábor <redacted> The final value of the counter of the "Scanning merged commits" progress line is always one less than its expected total, e.g.: Scanning merged commits: 83% (5/6), done. This happens because while iterating over an array the loop variable is passed to display_progress() as-is, but while C arrays (and thus the loop variable) start at 0 and end at N-1, the progress counter must end at N. This causes the failures of the tests 'fetch.writeCommitGraph' and 'fetch.writeCommitGraph with submodules' in 't5510-fetch.sh' when run with GIT_TEST_CHECK_PROGRESS=1. Fix this by passing 'i + 1' to display_progress(), like most other callsites do.
Sensible, I guess.
