Texinfo manual cautions users not to use tabs anywere in any texinfo file several times. For example following can be found: Caution: Do not use tabs in the lines of an example! (Or anywhere else in Texinfo, except in verbatim environments.) TeX treats tabs as single spaces, and that is not what they look like. In Emacs, you can use `M-x untabify' to convert tabs in a region to multiple spaces. Another section has similar warnings: * *Caution:* Last, do not use tab characters in a Texinfo file (except in verbatim modes)! TeX uses variable-width fonts, which means that it is impractical at best to define a tab to work in all circumstances. Consequently, TeX treats tabs like single spaces, and that is not what they look like in the source. Furthermore, `makeinfo' does nothing special with tabs, and thus a tab character in your input file will usually appear differently in the output. To avoid this problem, Texinfo mode in GNU Emacs inserts multiple spaces when you press the key. Also, you can run `untabify' in Emacs to convert tabs in a region to multiple spaces, or use the `unexpand' command from the shell. However emacs itself has tab character in many files as can be seen by the following 'find' command output whee the character between the single quote is a tab character. Shouldn't someone do `M-x untabify' on all these files? $ find . -name '*.texi' -exec grep -l ' ' {} \; ./doc/emacs/mule.texi ./doc/emacs/text.texi ./doc/emacs/emacs.texi ./doc/emacs/dired.texi ./doc/emacs/emerge-xtra.texi ./doc/emacs/vc1-xtra.texi ./doc/emacs/display.texi ./doc/emacs/sending.texi ./doc/emacs/fortran-xtra.texi ./doc/emacs/custom.texi ./doc/emacs/buffers.texi ./doc/emacs/basic.texi ./doc/emacs/building.texi ./doc/emacs/msdog.texi ./doc/emacs/help.texi ./doc/emacs/rmail.texi ./doc/emacs/calendar.texi ./doc/emacs/xresources.texi ./doc/emacs/programs.texi ./doc/emacs/search.texi ./doc/emacs/frames.texi ./doc/emacs/misc.texi ./doc/emacs/files.texi ./doc/emacs/trouble.texi ./doc/emacs/mark.texi ./doc/emacs/killing.texi ./doc/emacs/maintaining.texi ./doc/emacs/screen.texi ./doc/emacs/mini.texi ./doc/emacs/abbrevs.texi ./doc/lispref/text.texi ./doc/lispref/vol1.texi ./doc/lispref/display.texi ./doc/lispref/os.texi ./doc/lispref/elisp.texi ./doc/lispref/tips.texi ./doc/lispref/loading.texi ./doc/lispref/windows.texi ./doc/lispref/debugging.texi ./doc/lispref/vol2.texi ./doc/lispref/edebug.texi ./doc/lispref/functions.texi ./doc/lispref/keymaps.texi ./doc/lispref/internals.texi ./doc/lispref/sequences.texi ./doc/lispref/compile.texi ./doc/lispref/frames.texi ./doc/lispref/numbers.texi ./doc/lispref/processes.texi ./doc/lispref/commands.texi ./doc/lispref/files.texi ./doc/lispref/minibuf.texi ./doc/lispref/eval.texi ./doc/lispref/syntax.texi ./doc/lispref/strings.texi ./doc/lispref/searching.texi ./doc/lispref/abbrevs.texi ./doc/misc/ebrowse.texi ./doc/misc/forms.texi ./doc/misc/smtpmail.texi ./doc/misc/cl.texi ./doc/misc/pgg.texi ./doc/misc/sasl.texi ./doc/misc/viper.texi ./doc/misc/dired-x.texi ./doc/misc/sem-user.texi ./doc/misc/sc.texi ./doc/misc/semantic.texi ./doc/misc/gnus-faq.texi ./doc/misc/ede.texi ./doc/misc/sieve.texi ./doc/misc/faq.texi ./doc/misc/org.texi ./doc/misc/vip.texi ./doc/misc/autotype.texi ./doc/misc/pcl-cvs.texi ./doc/misc/reftex.texi ./doc/misc/idlwave.texi ./doc/misc/speedbar.texi ./doc/misc/eieio.texi ./doc/misc/epa.texi ./doc/misc/nxml-mode.texi ./doc/misc/widget.texi ./doc/misc/flymake.texi ./doc/misc/mh-e.texi ./doc/lispintro/emacs-lisp-intro.texi In GNU Emacs 23.1.1 (i486-pc-linux-gnu, GTK+ Version 2.18.3) of 2010-03-25 on palmer, modified by Debian Windowing system distributor `The X.Org Foundation', version 11.0.10604000 configured using `configure '--build=i486-linux-gnu' '--host=i486-linux-gnu' '--prefix=/usr' '--sharedstatedir=/var/lib' '--libexecdir=/usr/lib' '--localstatedir=/var/lib' '--infodir=/usr/share/info' '--mandir=/usr/share/man' '--with-pop=yes' '--enable-locallisppath=/etc/emacs23:/etc/emacs:/usr/local/share/emacs/23.1/site-lisp:/usr/local/share/emacs/site-lisp:/usr/share/emacs/23.1/site-lisp:/usr/share/emacs/site-lisp:/usr/share/emacs/23.1/leim' '--with-x=yes' '--with-x-toolkit=gtk' '--with-toolkit-scroll-bars' 'build_alias=i486-linux-gnu' 'host_alias=i486-linux-gnu' 'CFLAGS=-DDEBIAN -g -O2' 'LDFLAGS=-g' 'CPPFLAGS='' Important settings: value of $LC_ALL: nil value of $LC_COLLATE: nil value of $LC_CTYPE: nil value of $LC_MESSAGES: nil value of $LC_MONETARY: nil value of $LC_NUMERIC: nil value of $LC_TIME: nil value of $LANG: en_US.UTF-8 value of $XMODIFIERS: nil locale-coding-system: utf-8-unix default-enable-multibyte-characters: t Major mode: Mail Minor modes in effect: diff-auto-refine-mode: t shell-dirtrack-mode: t which-function-mode: t display-time-mode: t tooltip-mode: t tool-bar-mode: t mouse-wheel-mode: t menu-bar-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t blink-cursor-mode: t global-auto-composition-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t line-number-mode: t transient-mark-mode: t Recent input: C-c c f i n d SPC .
