Git config: add "ci" alias/modified checkout-indexf18

Superhandy in case on convoluted patchset regarding the same file,
which is being reversed-engineered from a bulk change and one wants
to retest each isolated changeset for not breaking expectations...
(at least in the case that such properties can be investigated
solely on this file, without the context that may refer to it,
otherwise the whole tree has to be somehow exported elsewhere)

Note the "${@/#/$GIT_PREFIX}" trick that should probably be
applied for all bang-aliases.
