[bug report] underscores in table cell not visible

Hi together,
As recommended on http://www.pgadmin.org/support/list.php, I'd like to
report a bug in pgAdmin 1.18.1 running on Ubuntu 13.10 with Linux
3.11.0-14-generic. If the user enters data including and underscore in a
column of type text, the underscore is not visible in the table data
table. It looks like a space, e.g. <tt>bus_stop</tt> is displayed as
<tt>bus stop</tt>. If the user doesn't have editing/writing permissions,
he_she doesn't have any chance to find out what the string is without an
external tool.

Kind regards,
Karl-P. Richter
