man zsh, zshall fix

+++ This bug was initially created as a clone of Bug #1066537 +++

Description of problem:

In COMPATIBILITY section of zsh(all) man page doesn't cover that sh emulation is triggered also if the first letter of the name by which it was invoked is 'b'.

However in the code ./zsh-4.3.10/Src/options.c the intention is clear:

void
emulate(const char *zsh_name, int fully)
{
    char ch = *zsh_name;

    if (ch == 'r')
        ch = zsh_name[1];

    /* Work out the new emulation mode */
    if (ch == 'c')
        emulation = EMULATE_CSH;
    else if (ch == 'k')
        emulation = EMULATE_KSH;
    else if (ch == 's' || ch == 'b')
        emulation = EMULATE_SH;
    else
        emulation = EMULATE_ZSH;

    if (fully)
        emulation |= EMULATE_FULLY;
    installemulation();
}
