[tex-k] Typos in errata.twelve (and Volume E?)

[胡亚捷 (Hu Yajie)]

Hi karl,

The file errata.twelve is supposed to have the final corrections to Volume E,
since the 2021 tuneup only affects Volumes A--D.

However, two of the corrections do not match the latest CM files on CTAN:

(1) Page E125, line -3 is said to have been changed to:

    draw z1-flourish_change{up}+(0,.15asc_height){up}
      ...{right}(z1+(2u,0))---z6...{down}z7;  %  upper bar

The real program in calu.mf, lines 85--86 lacks the first `{up}' and uses
`-' in place of the second `+':

    draw z1-flourish_change+(0,.15asc_height){up}...{right}(z1-(2u,0))
            ---z6...{down}z7;  %  upper bar

(2) Page E377, lines -3 and -4 is said to be replaced with:

    path p_; p_= z$$l{z at 1-z$$l}...darkness[z at 1,.5[z at 2,z$$l] ]...z at 2
      ---z$l--z$r--z at 0--z$$r--cycle;
    if (y$$>y$) <> (ypart precontrol 1 of p_ > ypart postcontrol 1 of p_):
      p_=z$$l{z at 1-z$$l}...darkness[z at 1,.5[z at 2,z$$l] ]
       ---z$l--z$r--z at 0--z$$r--cycle; fi
    filldraw p_; % arm and beak

The real program in cmbase.mf, lines 108--113 uses `:=' for the second
assignment to p_.

Did these errors affect the latest printings of Volume E, or are they only
present in errata.twelve?

By the way, if you have time, here are some errors in earlier errata files:
