[tex-k] Error in TeX The Program: tabskip glue is not marked as such

[Igor Liferenko]

Hi all,

Consider the following example:

    \tabskip=0pt plus10pt \halign to200pt{&#\hfil\cr
      \hbox to50pt{}&\hbox to60pt{}\cr}
    \end

The log is:

    \hbox(0.0+0.0)x200.0, glue set 3.0
    .\glue(\tabskip) 0.0 plus 10.0
    .\unsetbox(0.0+0.0)x50.0
    .\glue(\tabskip) 0.0 plus 10.0
    .\unsetbox(0.0+0.0)x60.0
    .\glue 0.0 plus 10.0

The last glue *is* tabskip glue, and thus should be marked as such.
More so that the correct log is on p.302 of TeXbook.

Regards,
Igor
