Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
updated for version 7.3.926 Problem: Autocommands are triggered by setwinvar() et al. Missing BufEnter on :tabclose. Duplicate WinEnter on :tabclose. Wrong order of events for :tablose and :tabnew. Solution: Fix these autocommand events. (Zyx)
