urlmatch.c: recompute pointer after append_normalized_escapes
When append_normalized_escapes is called, its internal strbuf_add* calls can
cause the strbuf's buf to be reallocated changing the value of the buf pointer.
Do not use the strbuf buf pointer from before any append_normalized_escapes
calls afterwards. Instead recompute the needed pointer.
