Description:
------------
There is an error when parsing php_value arguments when value is separated from name w/o space. Offending code is:

htscanner.c(99):

value = strchr(name, ' ');
if (value) { ... }

Reproduce code:
---------------
php_value variable_name\tvalue

Expected result:
----------------
variable_name set to value

Actual result:
--------------
variable_name ignored as value is null (no space between variable_name and value; only tabs).

Quick & dirty hack is to:

diff -urN htscanner-0.8.1-2/htscanner.c hts-m/htscanner.c
--- htscanner-0.8.1-2/htscanner.c       2007-03-23 12:31:59.000000000 +0100
