Issue1588

In the Linux jython script (under src/shell/jython in SVN), line 32 uses this command:

    if expr "$link" : '^/' > /dev/null; then

The '^' here is redundant, because expr implicitly matches from the beginning of the string. On some systems, like my RHEL 5.4 system, this produces a warning on the command line:

[rshaffer@rshaffer-dev1 ~]$ jython
expr: warning: unportable BRE: `^/': using `^' as the first character
of the basic regular expression is not portable; it is being ignored

It doesn't hurt anything, but the warning is ugly, and it's easy to fix. Simply remove the '^' character from the regex.
