Web: inbox/gcc-bugs broken links (for all bugzilla mails)

[Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>]

Hi!

When i direct my browser to
 https://inbox.sourceware.org/gcc-bugs/
i get 404 for every link there.

ATM this renders to e.g.:
---8<---
[Bug fortran/66973] New: Incorrect resolution of generic interface with TYPE(C_PTR)
 2023-04-12 18:48 UTC  (2+ messages)
` [Bug fortran/66973] "
---8<---
source:

href="bug-66973-4-10qXbFF8QB@http.gcc.gnu.org%2Fbugzilla%2F/T/#u">[Bug fortran/66973]</a> &#34;
---8<---

The first link yields a 404
  https://inbox.sourceware.org/gcc-bugs/bug-66973-4@http.gcc.gnu.org%2Fbugzilla%2F/T/#t
and the second link likewise returns 404
  https://inbox.sourceware.org/gcc-bugs/bug-101018-4-9OS85Mwt0G@http.gcc.gnu.org%2Fbugzilla%2F/T/#u

Instead of the 404, i would have hoped to see the contents
of something like
https://gcc.gnu.org/pipermail/gcc-bugs/2023-April/818551.html
for the first link
and for the second (probably) gcc.gnu.org/PR66973#c7

Note that this 404 seems to happen to all bugzilla mails, e.g. in
https://inbox.sourceware.org/overseers/
there is "[Bug Infrastructure/29619] New: Setup gitolite for projects"
which points to
https://inbox.sourceware.org/overseers/bug-29619-14326@http.sourceware.org%2Fbugzilla%2F/T/#t
which also gives a 404.

PS: Currently we have an URL rewrite for gcc.gnu.org/ for
    something like ^/PR([0-9]+) /bugzilla/show_bug.cgi?id=$1
    Could we please also support rewrites of lowercase "pr" for that's
    easier to type on virtual keyboards?

thanks!
