Project prefix directory not calculated correctly with Mercurial repository

[GoogleCodeExporter]

What steps will reproduce the problem?
1. mkdir test
2. cd test
3. hg init
4. touch file.h
5. cpplint.py file.h

What is the expected output?
The #ifndef header guard should be relative to project home directory.

stomic@dell07-desktop:~/tmp/test$ python ~/bin/cpplint.py file.h 
file.h:0:  No copyright message found.  You should have a line: "Copyright 
[year] <Copyright Owner>"  [legal/copyright] [5]
file.h:0:  No #ifndef header guard found, suggested CPP variable is: FILE_H_  
[build/header_guard] [5]
Done processing file.h
Total errors found: 2

What do you see instead?

The #ifndef header guard has an absolute path.

file.h:0:  No copyright message found.  You should have a line: "Copyright 
[year] <Copyright Owner>"  [legal/copyright] [5]
file.h:0:  No #ifndef header guard found, suggested CPP variable is: 
_HOME_STOMIC_TMP_TEST_FILE_H_  [build/header_guard] [5]
Done processing file.h
Total errors found: 2

What version of the product are you using? On what operating system?
trunk of cpplint.py
