strip leading/trailing spaces from `-v` params

[VladimirAlexiev]

Take this query

select ?x ?p ?y
where {
    service <x-sparql-anything:> {
      fx:properties fx:location $_file; fx:media-type "text/plain"; fx:txt.split "\n".
      [] fx:anySlot ?line.
      ?x ?p ?y
    }
}

This invocation returns the file lines:

sparql-anything -q test.rq -v file=my.txt

This invocation returns the list of files in cwd:

sparql-anything -q test.rq -v file= my.txt

The only difference is that there is a space after =.
IMHO that is confusing and undesirable.

If someone really wants a leading space in a param,
maybe a call like this could work: -v 'mySpace= ... and more... '

Why would I want space after =? Eg to autocomplete a filename, if I haven't setup special rules for sparql-anything

I would have expected the entire value to be void, with an unquoted space. However, it's trivial to trim values.

The arguments are passed as a list to the main method, so it is not that trivial. Of course, one could preprocess all arguments and join two when the previous ends with an equal sign, but frankly, it seems overkill (also, to be consistent, one should support cases where there are spaces before the = as well...).
However, on my terminal, autocompletion works after typing = ... what terminal are you using?

To troubleshoot:

$ java -jar sparql-anything-....jar -Dorg.slf4j.simpleLogger.log.io.github.sparqlanything.cli=debug arg1 arg2 arg3
[main] DEBUG io.github.sparqlanything.cli.SPARQLAnything - SPARQL anything
[main] DEBUG io.github.sparqlanything.cli.SPARQLAnything - args: [arg1, arg2, arg3]
[main] ERROR io.github.sparqlanything.cli.SPARQLAnything - SPARQL syntax error (or query file does not exists): Missing required option: q

[VladimirAlexiev]

I use bash (and there is some breakage in my autocomplete rules, unrelated to FX...).

I'll look for an option to treat = like a space: although that's a valid char in a filename (no escaping necessary), I haven't seen many filenames using it
