Hello!

I wondered today once more why the mode-line of a *compilation* buffer  
with column-number-mode on showed "??" as line number. A discussion on  
the Help-gnu-emacs list with Eli Zaretskii revealed:

This buffer switching did not enable the line numbers, maybe because  
of only changing between two buffers in the same frame. Meanwhile,  
having line-number-display-limit-width increased to an insane value of  
62,500 t\x05he line numbers counter works continuously. A new default  
value of 24 K should be OK – this is the maximal line length I almost  
encountered while compiling QT4. The line counter seems efficient  
enough that I did not encounter any loss in the speed of compilation  
or more heat produced by the CPU of my portable.

Up-to-date shell interpreters support command line lengths of 64 K,  
maybe even 128 K, to support software like QT4 or GTK+2 or based on  
these, so GNU Emacs should also update.
