introduce jump_pattern option

[QiBaobin]

Sometime, we don't have line and column information in context, like fd output, log etc.
Let's extract an option jump_pattern to let other use cases can override it.

to be clear, file:line:col and file:line are already supported.
Whether we want to support file, maybe, I'm not sure.
Do you have a use case in mind?
Note that it should be possible to create a buffer-local jump alias to your preferred implementation.
The LSP plugin uses this technique for example.
Also, if you want to support file, you probably want to do the same to jump-select-next and jump-select-previous (also those can be customized by means of aliases).

We only support file:line: currently, it doesn't recognize the pattern without last :.

One of my use case is that finding some files using fd or rg -l, look at them and open some of them. I don't know if there is a better workflow.

define-command -params 1.. -docstring "find files" fd %{
    require-module fifo
    evaluate-commands -try-client %opt{toolsclient} %{
        fifo -name "*fd*" fd -tf %arg{@}
        require-module jump
        hook buffer NormalKey <ret> jump
    }
}

do you think it's a better idea if I extract an option jump_file_pattern so that I can override it in my command and jump-next/previous can also use it?

@krobelus , I reverted the pattern and introduced an option instead, could you take another look?
