request: allow passing -X <strategy-option> to git checkout <path> to auto-solve merge conflicts

Hi, stumbling upon this again and again, so decided to write finally,

while in conflicting state, the only thing we can do to auto-pick one or another side of conflict is passing --ours/--theirs option to git-checkout: git checkout --ours/--theirs <path>

The problem is - it doesn't actually do a _merge_, i.e. you lose all non-conflicted changes.

There is no easy way to solve that currently without third-party tools.

Proposal: Shell we add -X <strategy-option> to git checkout <path> to allow it do a merge and _actually solve_ merge conflicts? That would be in-pair with other commands taking the option already: git-merge, git-rebase, (etc.?)
