    Add exp10(), for symmetry.

    We've got log, log2 and log10; so if we have exp and exp2, we should
    have exp10. Just because the C standard didn't see fit to include this
    one doesn't mean I shouldn't either.

    Rename the file-reading keywords to end in 'file:'.

    'base10file:' fits better with 'base10fd:', and leaves the bare
    'base10:' free for another purpose which I'm about to make up.

    Support input literals in any base.

    This takes over the 'base2:', 'base7:' etc syntax which I just moved
    the file-reading functionality away from, because it makes more sense
    to have this syntax be used for immediate literals.

    In this mode, no exponent character is recognised, because there's no
    well known convention for it and because the exponent base would be
    confusing (in that even in existing convention it doesn't reliably
    match the number base).

    Fix documentation error for -d in IEEE mode.

    In that context it counts bits, not digits; I mis-documented it.

    Special-case pow(rational,integer).

    This family of computations previously hung annoyingly, causing me to
    have to type silly things like 0x1p-123 or 1e100 when I really wanted
    to write 2^-123 or 10^100.

    Make -n apply in -c -l mode.

    -n ought to apply to any output which appears all on one line. But it
    still doesn't make sense to apply it to ordinary -c mode, or to -C.
