[issue19948] POSIX semantics of PATH search in execvpe is not respected

[Stéphane Glondu]

Stéphane Glondu added the comment:

> os.execvp calls os._execvpe which calls posix.execv which calls execv. At least that's how I think it works.

I am not contesting that. This bug is about the "search the command in PATH" part. More precisely, the fact that os.execvp continues the search after execv fails.
