[search path] behavior difference.

[serge]

hello

There is a difference in the way "search path" is handle between 
m4-1.4.2  and  m4-1.4.14.

  - With m4-1.4.2   each m4 file that is include will be search by 
default in the current path and each path include by -I option.

  - With m4-1.14   only the first m4 file will be search in current and 
path include by -I option,  all other m4 file will be search in the path 
match by the first include m4 file.


It's like there is some path cache in operation somewhere.
