Log Message:
Update fhist to 1.16.
Based on patch provided in PR 35539.
And I made two modification related to pkgsrc.

PKGSRC CHANGES:
   Make document & nls files to be installed into standard location.
   Add test target.

RELEASE NOTES:
   Version 1.16 (20-Dec-2005)
       * There is a new fmerge -ignore-identical-conflicts option which may be
       used to suppress logical conflicts in which the same thing is done by
       both variants. This is often a better match for users' expectations for
       merging source code.

   Version 1.15 (8-Nov-2005)
       * There is a new fcomp -no-binary option, which may be used to prevent
       the comparison of binary files, instead it treats them both as empty.

       * A small build problem on MacOS X has been fixed.

   Version 1.14 (8-Jun-2004)
       * The ./configure script now understands the --with-nlsdir option, so
       that you can place the .mo files.

       * The fhist(1) program is now able to cope with numeric modules names.

       * The occasional false negative from test 26 has been fixed.  It was
       failing for some users because of message translation
       (internationalization) issues.
