Subject: rev-list option parser fix.
X-Git-Tag: v1.4.0-rc1~239^2~13
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=7594c4b2d7cc81f806453402aefe1bf71ae6dd53;p=git.git

rev-list option parser fix.

The big option parser unification broke rev-list the big way;
this makes it use options from the parsed revs structure.
