etags -f /dev/stdout enhancement request

[Lyndon Nerenberg {VE6BBM}]

etags treats "-f -" as a special case in that the pathname of the
source file is not made relative to the location of the tags file.
Specifying "-f /dev/stdout" defeats this check, resulting in bogus
source file pathnames in the tags file. Enclosed is a patch that causes
"-f /dev/stdout" to be treated the same as "-f -" is.

This diff is against the 21.2 released sources.
