/*----------------------------------------------------------------------
Paste together two pieces of a file name path
Args: pathbuf -- Put the result here
first_part -- of path name
second_part -- of path name
Result: New path is in pathbuf. No check is made for overflow. Note that
we don't have to check for /'s at end of first_part and beginning
of second_part since multiple slashes are ok.
BUGS: This is a first stab at dealing with fs naming dependencies, and others
still exist.
