OK, that would explain it, I think.

Possible yes, easy no.

The "~" part is trivial; that's expanded inside the C program anyway.
The harder thing is that helper strings can be arbitrary shell commands
(if you start them with "!"), so we decide at parse time whether to
stick the "git credential-" in front and then always treat it as a shell
command, rather than carrying through the knowledge that it doesn't need
a shell. So switching that would ripple through the whole call stack and
the data structures.

Definitely not impossible, and not even _hard_, but it's not like a
one-liner change.
