I'm having a problem...why does bash choke on this:

	cmdname=`_=\`/bin/basename $0\`; /bin/expr $_ : '\(.*\),v' \| $_`

Here's some debug info from bash:

	+++ /bin/basename ./tst
	++ _=tst
	++ /bin/expr : \(.*\),v |
	expr: syntax error

$_ isn't being assign anything from /bin/basename.

This works fine with /bin/sh:

	+ cmdname=
	+ /bin/basename ./tst 
	_=tst
	+ /bin/expr tst : \(.*\),v | tst 
	cmdname=tst

Thanks.
