/* Modified September, 1995, Amy A. Lewis
* 1: removed
all file-locking dreck.
Unnecessary
* 2: Fixed bug
that made fortune -f report a different list than
* fortune with any other parameters, or
none, and which forced
* the program to read only one file
(named 'fortunes')
* 3: removed
the unnecessary print_file_list()
* 4: Added
"OFFDIR" to pathnames.h as the directory in which offensive
* fortunes are kept. This considerably simplifies our life
by
* permitting us to dispense with a lot of
silly tests for the string
* "-o" at the end of a
filename.
* 5: I think
the problems with trying to find filenames were fixed by
* the change in the way that offensive
files are defined. Two birds,
* one stone!
* 6: Calculated
probabilities for all files, so that -f will print them.

/* Modified May 1997, Dennis L. Clark
(dbugger@progsoc.uts.edu.au)
* + Various
portability fixes
* + Percent
selection of files with -a now works on datafiles which
* appear in both unoffensive and
offensive directories (see man page
* for details)
* + The -s and -l
options are now more consistant in their
* interpretation of fortune length
* + The -s and -l
options can now be combined wit the -m option

/* Modified August 2001, Takahiro
Nagao(nyagao@longtail.co.jp)
* + ported to Windows
* + if -n NUM is too small or too large,
now it doesn't cause infinite loop
* (see init_prob())
* + -f xx% dir now should report correct
percentage (see print_list())
* + added -z to report file and pos
