Subject: 27.0.50; Emacs `compile' command does not handle remote (over
 TRAMP) file name correctly
Date: Tue, 17 Dec 2019 20:44:28 +0800

Re-produce steps:

1. `find-file' to my project root directory on a remote machine,
   namely, "/scp:vm00:pmdk-balloon/".
2. `M-x compile', and give compile command "make".
3. (Previously I have injected some typos in some of my source files,
   say "obj.c").
4. In the *compilation* buffer, the "obj.c" file appears.  But when I
   click the underlined text (or <RET> on it), an error occurs in the
   minibuffer:

   "Find this error in (default obj.c): /scp:vm00:/System/Volumes/Data/home/fan/pmdk-balloon/src/libpmemobj"

   The "/System/Volumes/Data/" is actually a path on my local machine.
5. To further confirm, I use `C-u C-x =' on the underlined text in the
   *compilation* buffer.  The "compilation-message" text property shows:

   #s(compilation--message
   (nil 42
        (("../common/vec.h" "/scp:vm00:/System/Volumes/Data/home/fan/pmdk-balloon/src/libpmemobj")
         nil
         (42 #1))
        nil nil)
   0 nil)

It appears that when compile.el was handling the remote path, it
mixed-up part of my local machine path with the
remote machine path, resulting the error.

I use Edebug to instrument `compilation-get-file-structure' and
then `file-truename' to find when my local path "/System/Volumes/Data/"
is inserted, here is a backtrace:

  lines started with a "*" is what I think important.

  compilation--parse-region(1941 #<marker at 2809 in *compilation*>)
  compilation--ensure-parse(2462)
  compilation-filter(#<process compilation> "In file included from ../common/vec.h:42,\n        ...")

Then I find that in my environment, `(file-symlink-p "/home")' is
evaluated to "/System/Volumes/Data/home".  Now I stuck here since I know
little about TRAMP and how a remote file path should be handled.

Do you have any suggestion or idea to fix this bug?  Thanks in advance
for your time.
