That is a dangeous thought.  I'd understand if it were internally
two step process, i.e. (1) the first pass finds commits that hits
the --grep criteria and then (2) the second pass does "--contains"
for all the hits found in the first pass using existing code, but
still, this operation is bound to dig all the way through the root
of the history when asked to find something that does not exist.

You should at least feed all --contains to a single invocation of
"git branch".  They are designed to be OR'ed together.
