Using the master branch I wrote a small `echo` utility and failed to
reproduce the problem:
```c
#include <stdio.h>
int main(int argc, char **argv){
for(int i = 1; i < argc; ++i){
fputs(argv[i], stdout);
if(argc - i != 1){
putchar(' ');
}
}
putchar('\n');
}
```
Running `a.exe *` in CMD printed a list of all files, but running `a.exe
stash@{0}` merely prints `stash@{0}`.
The globbing feature is not provided by us, but by MSVCRT. You can look
into our source code to tell how we involve `__getmainargs()`, which is
imported from MSVCRT and out of our control. However it does not strip
braces.
MSYS2's 'echo.exe' suffers from this problem, anyway:
```text
C:\Users\lh_mouse>"echo.exe" stash@{-1}
stash@-1
```
But I have no idea what they did to the CRT.
