Commit 486270dc4f80f05a676ac87caa3a9a19929f358e

Carlos Martín Nieto 2015-10-14T16:49:01

revwalk: make commit list use 64 bits for time We moved the "main" parsing to use 64 bits for the timestamp, but the quick parsing for the revwalk did not. This means that for large timestamps we fail to parse the time and thus the walk. Move this parser to use 64 bits as well.
