[PATCH] Improve pull request URL matching regex

[Konstantin Ryabitsev]

Existing regex was missing several important use cases, such as:

- tag/branch info wrapping to the next line, e.g.:

----
are available in the Git repository at:

  https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux.git/
tags/v5.4-next-soc

----
(see example: https://patchwork.kernel.org/patch/11236893/)

- tag/branch info being wrapped to the next line with a backslash, e.g.:

----
are available in the Git repository at:

  https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux.git/ \
  tags/v5.4-next-soc

----
(no example, but I've seen this before)

The proposed change deals with these edge-cases.
