format: fix precision field leading zero problems.

* stream.c (formatv): Do not recognize multiple leading zeros
as a single one; once the zero flag is set, if another zero is
seen, it must be treated as one of the digits specifying the
precision value. New requirement: before processing a format
specifier, check for the situation that the leading zero
has been specified, but no precision. Convert this situation
to that of a precision of zero being given, with no leading
zero.

* txr.1: Document the ambiguity around the leading zero and
how it is being handled when only the leading zero flag is
given, and no actual precision. Add a note about what happens
when zero precision is specified in ~a in conjunction with
a floating-point value. Misspelled "pas" word fixed.
