From: James Touton <bekenn@xxxxxxxxx> Fixes several Python diagnostics about invalid escape sequences. The diagnostics appear for me in Python 3.12, and may appear in earlier versions. The fix is to use raw string literals so that backslashes are not interpreted as introducing escape sequences. Raw string literals are already in use in this file, so adding more does not impact toolchain compatibility. Signed-off-by: James Touton <bekenn@xxxxxxxxx> --- git-p4: use raw string literals for regular expressions Changes since v1: * Updated commit message to include the Python version where the diagnostics were observed.
