Hmmm.  That change would cause warnings for users of pexecute.  On the
other hand pexecute has always returned a pointer to a string
constant, so it's always been a requirement for the caller to not
modify the returned string.  And of course pexecute is now an obsolete
interface, and code should now call pex_init/pex_run or pex_one.  So
I'm on the fence on this.  Any other opinions?

This is OK.  Thanks.
