The previous regex miss a situation that a new file is added after
the map file. It will starts with '/dev/null' instead of 'a /', so
all the content in the patch file after 'map' will be considered in
the symbol map file. Also, a second regex matching is used for map
and other files, the '^map' in square brackets is not quite exact
the same with the design even if it works.
