bug#51882: Handle GCC's -fanalyzer output in M-x compile

[Philip Kaludercic]

Tags: patch


GCC's -fanalyzer generates tree-like output, with some file references
being indented like this

--8<---------------cut here---------------start------------->8---
      |file.c:42
--8<---------------cut here---------------end--------------->8---

M-x compile appears to assume this means the file name is

    "     |file.c",

not "file.c".  The following patch would fix this behaviour.  

If accepted, should it be applied to emacs-28 or master?
