Revised version of workers/41523.
---
The original patch used ${(e)} but that would execute command substitutions in
cases such as «--git-dir=$(pwd)».  ${(Q)${~foo}} doesn't have that problem.

The problem it does have is that «--git-dir=$HOME/foo» doesn't expand $HOME.
A syntax that performs "safe" expansions — i.e., those that can be done without
running arbitrary code — would be useful, both in completion and in widgets
(e.g., z-sy-h would find that useful).

For 5.9.

Cheers,

Daniel
(Someone ran into the problem and the fix on IRC.)

Following a conversation of IRC I changed this line to account for the case
that $PREFIX is an absolute path.  Revised patch:

[adding a marker line for git am -c]
