The problem happens when both of the following conditions are true:

  . the command being invoked is a batch file (git.cmd in this case)

  . the directory where it lives included parentheses

I cannot find a workable solution for this situation; the error
happens even if the batch file is invoked via the system shell.
Suggestions for solving this are welcome.  The relevant function is
w32proc.c:sys_spawnve.

Unless someone can suggest how to fix this, I'm inclined to tag this
problem as "wontfix", and suggest that Windows users do not install
such commands in a directory whose name includes parentheses.
