Hi,

these days I'm working on bug#31704. The point is, that for searching o= f
programs, always `exec-path' (a list of local directories) is taken, even if the shell runs on a remote host. Therefore, I propose a new
function `remote-exec-path'. In case of a remote `default-directory'= ;,
the function returns a list of directories which belong to that
host. Implemented via file name handlers. For a local
`default-directory', `exec-path' is returned.

And while we are at this, a second new function `remote-executable-find'= ;
comes to mind. Like `executable-find', it returns the local absolute file name of a command, also determined by `default-directory'. This function doesn't need file name handlers, it would use
`remote-exec-path' for its implementation.

I don't need `remote-executable-find' for fixing bug#31704, but I remember that such a function has been asked for in the past.

Comments?

There have been multiple occasions where s= uch functions would have been handy for me, so I'm strongly in favor of= adding them. Thanks!=C2=A0
