This patches teaches git-submodule an option '--summary-limit|-n <number>' to limit number of commits for the summary. Number 0 will disable summary and minus number will not limit the summary size. For beauty and clarification, the last commit for each section (backward and forward) will always be shown disregarding the given limit. So actual summary size may be greater than the given limit. In the same super project of these patch series, 'git submodule -n 2 summary sm1' and 'git submodule -n 3 summary sm1' will show the same. --------------------------------------- $ git submodule -n 2 summary sm1 # Submodules modifiled: sm1 # # * sm1 354cd45...3f751e5: # <one line message for C # <one line message for B # >...
