Subject: bug#23400: Emacs 25.0.92.1: etags fails to handle file format generated by Exuberant Ctags 5.8 in etags emulation mode
Date: Fri, 29 Apr 2016 10:42:32 -0400	[thread overview]
Message-ID: <CA+OMD9iXZW9xKF5Z1gwV-Q9dr6J04EvON=a5yd9e7036UguMJw@mail.gmail.com> (raw)


[-- Attachment #1.1: Type: text/plain, Size: 1167 bytes --]

Exuberant Ctags allows one to generate what is said to be an etags
compatible TAGS file.
However, a call to list-tags fails on such a file because it includes 2
lines of file names per file rather than one.

Attached is a sample TAGS file that triggers the error with this call:
(list-tags "hmouse-key.el")
and an associated patch that fixes it.
