Comment(by terrell):
What is the problem/shortcoming with forcing {{{k<=happy<=m}}}?
And make the error message simply state that this has to be true for Tahoe
to succeed?
Document some easily-expected example settings and ramifications:
{{{k=3, happy=7, m=10}}} -- default
{{{k=1, happy=1, m=X}}} -- not recommended, no redundancy
{{{k=2, happy=2, m=X}}} -- friendnet, backup guaranteed (minimal
protection)
{{{k=3, happy=3, m=X}}} -- friendnet, backup guaranteed (better
protection)
etc...
