I wondered today once more why the mode-line of a *compilation* buffer =20= with column-number-mode on showed "??" as line number. A discussion on =20= the Help-gnu-emacs list with Eli Zaretskii revealed: > The code seems to remember that a window had long lines, and once that > happens, this window will not have line numbers, until you switch to > another buffer. This buffer switching did not enable the line numbers, maybe because =20 of only changing between two buffers in the same frame. Meanwhile, =20 having line-number-display-limit-width increased to an insane value of =20= 62,500 t=05he line numbers counter works continuously. A new default =20 value of 24 K should be OK =96 this is the maximal line length I almost =20= encountered while compiling QT4. The line counter seems efficient =20 enough that I did not encounter any loss in the speed of compilation =20 or more heat produced by the CPU of my portable. Up-to-date shell interpreters support command line lengths of 64 K, =20 maybe even 128 K, to support software like QT4 or GTK+2 or based on =20 these, so GNU Emacs should also update. -- Greetings Pete Upgraded, adj.: Didn't work the first time. --Apple-Mail-1--1253559 content-type: application/pgp-signature; x-mac-type=70674453; name=PGP.sig content-description: Signierter Teil der Nachricht content-disposition: inline; filename=PGP.sig content-transfer-encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) iEYEARECAAYFAks1I9sACgkQ+Z8cB9x5ExO+egCeJVF61SqGHFKU3HV7rbKV6385 43wAnR0lYUkt7PC7tnD8T61GoY5fCkUC =Iz3s -----END PGP SIGNATURE----- --Apple-Mail-1--1253559--
