Subject: read-tree --reset -u fix.
X-Git-Tag: v1.4.0-rc1~133^2~3
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=6d6776cb497ea7fbf5fe43912dbe3286f76c9933;p=git.git

read-tree --reset -u fix.

The previous commit makes -u to mean "I do want to remove the
local changes, just update it from the read tree" only for
one-way merge.  It makes sense to have it depend on the
"--reset" flag instead.
