cleanup: merge two trim functions to one
As a minor improvement make the trimmed string to stay at same start
address, so that trims can be safely done to pointers that are allocated and
need to be free'd later on.  There is no such case in this code, but it is
good idea to write functions the way they will not cause memory issues
if/when such use case happens.
