djc, I don't think we have this yet

I seem to recall we have this by now. Need to check.

Here's a new version of the patch, which is basically just a migration to the 
right location of the one below.

Yes, your missing something obvious: I didn't use my brain :)

I thought you were asking for different ssh commands (most often asked for to
give ssh options), not different remote hg calls.

While there is the possibility to fix many things using .bashrc (or whatever
shell's login script), but often it is not desired to change things on the
remote side.

I guess the best thing (next to providing a patch :)) would be to talk about
this issue in #mercurial on freenode or to talk on the mailing list about this.

That's fine, but how do I set the command per host?

So I have Machine1 which is normal and responds fine to "hg" as remotecmd... 
and Machine2 which is... shall we say strange, for reasons I do not control, 
and works optimally with a wrapper program "hgwrap" (which sets paths, which 
are not loaded on login.  As I said, weird machine).

I want "remotecmd.machine2 = hgwrap" in my ~/.hgrc so that the normal machines 
still stay normal.

I apologize profusely if I'm missing something obvious.

Why not?
You can have many "Host" sections in your .ssh/config, even if they all have the
same User and HostName set.

While I appreciate the suggestion, this doesn't (seem to) help for machines I 
don't control, where I only have one login?

You know that you can specify many options in your ~/.ssh/config?

For example I use this:
 Host hg hg.intevation.org
 User hg
 HostName hg.intevation.org
 IdentityFile ~/.ssh/id_dsa_hg
 IdentitiesOnly yes

So whenever I access the host "hg" or "hg.intevation.org" the real hostname used
is "hg.intevation.org" with the other options specified there.

I would like to be able to specify per-remote-host remotecmd options in my 
~/.hgrc file.  The diff to enable this is simple and small:

Other options, such as per-host&port may also be desirable?
