I just protected all the necessary characters with one more level of quoting.
The local shell will strip one level of quoting leaving you with:

    locate -r '\.ext$'

which is what you want.

Subject: [PATCH]$name[selector] breaks rightness of empty range with omitted
	second argument in range

Hi,

This is related to "[PATCH]$name[selector]:it should fail when any number
of 'selector' is out of range" thread discussed here roughly a year ago
(see http://mx.gw.com/pipermail/tcsh/2008-February/003923.html).

The patch breaks $name[selector-] functionality (the second argument is
omitted).

This situation is described in man page: "It is not an error for a range
to be empty if the second argument is omitted or in range.". But with the
patch the tcsh produces "argv: Subscript out of range." in this situation.

Try:
#!/bin/tcsh -f
echo $argv[1-]

The patch should be reverted or fixed (if you believe that $name[selector]
should fail when any number of selector if out of range - I'm not sure, because
man page doesn't state it).

The patch is part of tarball since tcsh-6.16.00.

Best regards,
Vitezslav Crhonek
