Convert '~/' when supplied in $package_dir

[danielbachhuber]

Fixes #119

[danielbachhuber]

@schlessera I'm not sure realpath() is the way to go because:

The running script must have executable permissions on all directories in the hierarchy, otherwise realpath() will return FALSE.

Thoughts?

[schlessera]

Maybe use our own helper functions, something like this: https://3v4l.org/9Ga8c

Drush uses this: https://github.com/webmozart/path-util

As it's very Unixy could just do something like

if ( '~/' === substr( $package_dir, 0, 2 ) && ( $home = getenv( 'HOME' ) ) ) {
	$package_dir = $home . substr( $package_dir, 1 );
}

[schlessera]

@gitlost Yes, I suggested a more robust version of that here: https://3v4l.org/9Ga8c

[danielbachhuber]

@schlessera @gitlost Updated. I went with the simpler approach to begin with.

[schlessera]

I'm not sure why you'd want to solve this partially only. It is highly probable someone will want to use a relative path with this as well, and just create a new bug report at that point.

Additionally, having ~ work, and not . or .. makes it even worse in that it is inconsistent as well.

[gitlost]

I don't see how a relative path or . or .. won't just work - just tried --dir=~/../blah and it worked...

[schlessera]

Oh, okay, I just assumed it would create issues as well. All good then.
