[PATCH] Use SHELL_PATH as hash bang in test suite askpass helper script.

[PATCH] Use SHELL_PATH as hash bang in test suite askpass helper script.

[Ben Walton]

The askpass script that is created for use by the test suite should
use SHELL_PATH for its hash bang instead of /bin/sh. Commit 5a4352024
introduced the use of idioms not supported in some legacy /bin/sh
implementations.

Sounds good.

This can just become:

  write_script askpass <<\EOF

which handles this for us (and you can get rid of the manual chmod then,
too).

[PATCH] Ensure SHELL_PATH is the hash bang for test suite askpass helper script.

[Ben Walton]

The askpass script that is created for use by the test suite should
use SHELL_PATH for its hash bang instead of /bin/sh. Commit 5a4352024
introduced the use of idioms not supported in some legacy /bin/sh
implementations.

Use write_script to ensure this happens automatically. This lets us
remove the chmod step as well, since write_script handles that.

Thanks, this looks good to me.

I'll leave out the "some legacy shells we do not support want to use
`command`" from the justification of this change.  Use of the
write_script helper is the right thing to do---$SHELL_PATH points at
the shell the user told us s/he wants to use, and that is a reason
enough for this change.  The reason why the user wants to use that
shell is immaterial.

Thanks.
