If you write something like this in 0.8.1 or older versions in Windows systems:
import $__dir__ + '/some/file.pashm'
you will get a error that says invalid path:
C:\my-app\C:\my-app\some/file.pashm
you expect for this path:
C:\my-app\some/file.pashm
but the path is C:\my-app\C:\my-app\some/file.pashm. actually, the C:\my-app is repeated 2 times.
Now, the import path is relative with current working directory instead of the main file directory.
The bug was related to checking relative/non-relative paths. this check was checking first
character of the path. if that is /, means it is a non-relative path. but in windows,
paths will be started with C:..., and bug was from this subject.
