Log Message:
Add wdiff functionality, which performs a word-by-word comparison
between two areas of memory, or between two files. This is
accomplished using two new functions, wdiff_mem() or wdiff_file(), and
results can either be retrieved by displaying them to stdout, to an
output file, or by using diff_get_diffs() to retrieve the results
in-memory.
Internally, the two files/areas of memory are split into separate
areas of memory with a word on each line, and the two areas of memory
are compared using diff_mem().
Comparisons can also be made in a case-insensitive manner.
In the comparison output, added text is displayed in {+ ... +}
delimiters, and deleted text is shown with [- ... -] delimiters.
Changes are displayed as a deletion and an addition.
+ Deleted text can be inhibited from display by using the -1 argument
to netwdiff(1).
+ Added text can be inhibited from display by using the -2 argument to
netwdiff(1).
+ Common text can be inhibited from display by using the -3 argument
to netwdiff(1).
(Don't blame me, these flags are the ones used by GNU wdiff.)
With thanks to Thomas Klausner for the nudge to create this.
