bug#33158: 26.1; some vc operations on 'src' files result in 'src: -- is not registered'

[Bob Hepple]

Odd indeed!

I'm using the most recent version 1.18 downloaded from gitlab e6acd942

Anyway:

$ src cat 2 tamborine.org # works fine but:

$ src cat 2 -- tamborine.org
src: -- is not registered

... so it looks like a disconnect between the 'src' doco and reality ie a bug in 'src'. I'll raise a bug report with esr.

'src' does not use 'getopt' nor 'optparse' etc - it parses the command line arguments itself. So I _think_ it's falling into one of the nasty edge cases inherent in that approach.

I have my workaround - I guess it's up to you if you want to apply it in vc-src.el for other users until esr fixes 'src'.

Thanks for your hard work on my favourite editor (since the mid-eighties!)

Cheers

Bob

This is odd since the "--" was added 4 years ago in baab20d by src's author,
and http://www.catb.org/~esr/src/src.html says:

    The token "--" tells the command-line interpreter that subcommands,
    switches, and revision-specs are done - everything after it is a
    filename, even if it looks like a subcommand or revision number.
