[PATCH v2 0/1] MR10675: scrrun: Implement IFolder and IFile ShortName and ShortPath.

[Francis De Brabandere (＠francisdb)]

Both get_ShortPath methods wrap GetShortPathNameW on the stored long path; get_ShortName extracts the last component of the resulting short path. Add matching tests comparing against GetShortPathNameW directly.

[PATCH v2 1/1] scrrun: Implement IFolder and IFile ShortName and ShortPath.

[Francis De Brabandere]

From: Francis De Brabandere <[e-mail]>

Both get_ShortPath methods wrap GetShortPathNameW on the stored long
path; get_ShortName extracts the last component of the resulting short
path. Add matching tests comparing against GetShortPathNameW directly.
