AVR: Fix overly long URLs in the printed PDF documentation.
The AVR backend's documentation now has shorter URLs that fit within page boundaries in the PDF.
The AVR backend’s documentation contained URLs that were too long and caused them to overflow page boundaries in the generated PDF. This commit shortens those URLs in doc/invoke.texi and doc/extend.texi to improve the readability of the printed documentation. This is primarily a cosmetic fix.
In Details
This commit modifies the Texinfo source files for the AVR backend's documentation. The changes are limited to shortening URLs in doc/invoke.texi and doc/extend.texi. Search terms: GCC AVR documentation Texinfo PDF
For Context
GCC's documentation is written in Texinfo, a documentation system from the GNU project that allows generating output in various formats, including HTML, Info, and PDF. This commit addresses a formatting issue in the PDF output for the AVR port of GCC, ensuring that URLs fit within the page margins for better readability.
