Output strange file path when there are multiple wav files

[Tomoki Imai]

Log displays strange verbose file path when there are multile wav files.
This issue is not critical, because it is just only annoying.

Here is my directory tree which contains two wav file named a01.wav and a02.wav.

.
├── bin
│   ├── julius-4.3.1
│   ├── julius-4.3.1.exe
│   └── yomi2voca.pl
├── License.md
├── models

├── segment_julius.pl
└── wav
    ├── a01.txt
    ├── a01.wav
    ├── a02.txt
    └── a02.wav

And when I run segment_julius.pl, it outputs like following.

-> perl segment_julius.pl                                                                              [~/Desktop/sk]
./wav/a01.wav
enter filename->..............................................................................................................................................................................................................................................................................................................................................................................................................................................................enter filename->1 files processed
Result saved in "./wav/a01.lab".
./wav//a02.wav
enter filename->.................................................................................................................................................................................................................................................................................................................enter filename->1 files processed
Result saved in "./wav//a02.lab".

The output contains file path ./wav//a02.wav, which is verbose.
./wav//a02.wav is equals to the simplified form ./wav/a02.wav, and it should output simplified version.

I confirmed this issue in Linux, but I think we can see it also in Windows.
