dehumanize_number

[Peter da Silva]

Looking at the FreeBSD man pages, the function that reverses the
effect of "humanize_number" is "expand_number" rather than
"dehumanize_number". The source code to bsd/libutil.h in your source
tree also lists "expand_number" but not "dehumanize_number". Code for
both variants are included, with no attempt at unifying them.

Is this somewhat confused situation intentional?
