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.
