[PATCH] Use nice names in conflict markers during cherry-pick/revert.

["Shawn O. Pearce" <spearce@spearce.org>]

Always call the current HEAD 'HEAD', and name the patch being
cherry-picked or reverted by its oneline subject rather than
its SHA1.  This matches git am's behavior and is done because
users most commonly are cherry-picking by SHA1 rather than by
ref name.
