RFR: 8341833: incomplete snippet from loaded files from command line is ignored [v2]

[Jan Lahoda]

> If JShell is run with a parameter that is a file, and the file ends with an incomplete snippet, the incomplete snippet is ignored.
> 
> For example:
> 
> t.jsh:
> class {
> 
> 
>  jshell  /tmp/t.jsh
> |  Welcome to JShell -- Version 21.0.5
> |  For an introduction type: /help intro
> 
> jshell>
> 
> 
> This PR proposes to produce an explicit error in this case:
> 
> $ jshell /tmp/t.jsh 
> Building target 'default (exploded-image)' in configuration 'linux-x86_64-server-release'
> Finished building target 'default (exploded-image)' in configuration 'linux-x86_64-server-release'
> Incomplete input: class {
> |  Welcome to JShell -- Version 25-internal
> |  For an introduction type: /help intro
> 
> jshell>
