Run executable files form the current directory

[ForNeVeR]

Enter a directory with the executable file (for example, npm.cmd). After that, in PowerShell:

PS> npm.cmd
Command 'npm.cmd' cannot be found. # And here goes the suggestion about calling it as .\npm.cmd
PS> .\npm.cmd # or ./npm.cmd
# Command executes

In Pash:

Pash> npm.cmd
# Command executes
Pash> .\npm.cmd
Command '\npm.cmd' not found.
  +CategoryInfo: ObjectNotFound, Reason: ParentContainsErrorRecordException
  +FullyQualifiedErrorId: CommandNotFoundException

The exception generated at Pash\Source\System.Management\Pash\Implementation\CommandManager.cs:125.
