shell-argfiles
The -Zshell-argfiles compiler flag allows argfiles to be parsed using POSIX
"shell-style" quoting. When enabled, the compiler will use shlex to parse the
arguments from argfiles specified with @shell:<path>.
Because this feature controls the parsing of input arguments, the
-Zshell-argfiles flag must be present before the argument specifying the
shell-style arguemnt file.
