sagemathgh-39326: [DOC] src/doc/fr/tutorial/conf.py: remove obsolete …
…latex work-around This work-around was needed with Pygments<1.0 hence has been obsolete for more than fifteen years. Here is the [relevant commit](/~https://github.com/pygments/pygments/commi t/14b9433c05086beb67aca7436a96d1e685787d93) from Pygments: ```text commit 14b9433c05086beb67aca7436a96d1e685787d93 Author: Georg Brandl <georg@python.org> Date: Fri Sep 12 00:28:08 2008 +0200 Don't define \at, \lb, \rb as escapes, but prepend commandprefix here too. ``` Update: it is possible early-history Sphinx had some hardcoded things nowadays imported dynamically from Pygments such as the contents of the file `sphinxhighlight.sty` one finds in the latex build directory (which does currently `\def\PYGZat{@}`). Indeed I also found a [similar commit at Sphinx](/~https://github.com/sphinx- doc/sphinx/commit/46544e4986fd2dbdf11d79897c18ef6623956db6), ```text commit 46544e4986fd2dbdf11d79897c18ef6623956db6 Author: Georg Brandl <georg@python.org> Date: Thu Sep 11 22:29:35 2008 +0000 Use a prefix to \at, \lb and \rb since they are probably often used command names. ``` which was part of [Sphinx 0.5 release](/~https://github.com/sphinx- doc/sphinx/releases/tag/v0.5) from November 2008. It is not fully clear to me why sagemath#8183 was raised in February 2010, but anyway I am very confident the issue does not exist at all if producing the PDF docs with a reasonable version of Sphinx. There is another conf.py with this work-around but sagemath#39325 already handles it. <!-- ^ Please provide a concise and informative title. --> <!-- ^ Don't put issue numbers in the title, do this in the PR description below. --> <!-- ^ For example, instead of "Fixes sagemath#12345" use "Introduce new method to calculate 1 + 2". --> <!-- v Describe your changes below in detail. --> <!-- v Why is this change required?
