Merge branch 'lt/logopt'
* lt/logopt: Fix "git log --stat": make sure to set recursive with --stat. combine-diff: show diffstat with the first parent. git.c: LOGSIZE is unused after log printing cleanup. Log message printout cleanups (#3): fix --pretty=oneline Log message printout cleanups (#2) Log message printout cleanups rev-list --header: output format fix Fixes for option parsing log/whatchanged/show - log formatting cleanup. Simplify common default options setup for built-in log family. Tentative built-in "git show" Built-in git-whatchanged. rev-list option parser fix. Split init_revisions() out of setup_revisions() Fix up rev-list option parsing. Fix up default abbrev in setup_revisions() argument parser. Common option parsing for "git log --diff" and friends
Diffstat (limited to 'revision.c')
