Subject: Fix TPAC shelf browser's previous link
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=d34ceebde716799df47e3dd10313ca45cd5c08ad;p=contrib%2FConifer.git

Fix TPAC shelf browser's previous link

Line fix suggested by Thomas Berezansky.

The cnoffset was strictly checking for values that start with a digit.
But negative numbers start with a "-" instead. Once this check was
changed, the previous link will continue to move further into negative
offsets.
