Hi Guys.
I am editing files remotely with tramp. Then I run gtags-goto-tag And I
am getting this error:

I have contacted the tramp author: Michael Albinus. Who have told me:
--8<---------------cut here---------------start------------->8---
The backtrace shows that call-process is applied. This runs always a
*local* process; Tramp is not involved.
--8<---------------cut here---------------end--------------->8---
As a workaround. I have tested etags and ggtags.el. Let me know If You
need more information about the issue.
Best Regards. AR
