Thanks!  Your base91 encoding is very nice, but it's non-standard and it
includes the colon, which makes the resulting strings unsuitable for
/etc/passwd format files.  Would you considering switching to the
encoding proposed here? -

An implementation of it is available here:

Also, GPLv3+ is too strict to my taste, especially for library code
like this.  I think the license should be no stricter than Colin's
original (that is, 2-clause BSD).
