The second loop in the remove_space function doesn't check for walking
back off of the start of the string while setting white space to 0.

This fix exits this loop once the pointer is before the (updated) beginning
of the string.

There are cases when, if you pass a NULL UI_METHOD, the called
function will use an internal default.  This is well and good, but
there may be cases when this is undesirable and one would rather send
in a UI that does absolutely nothing (sort of a /dev/null).  UI_null()
is the UI_METHOD for this purpose.

more sensible.
