IndexError: list index out of range in pattern_to_regex #44

Hi @sanderland, I can't reproduce this error. Based upon the line you referenced, if there's a bug this should trigger it: >>> from pathspec.patterns.gitwildmatch import GitWildMatchPattern
>>> GitWildMatchPattern.pattern_to_regex("!'n")
("^(?:.+/)?\\'n$", False)
>>> GitWildMatchPattern.pattern_to_regex("!'n\n")
("^(?:.+/)?\\'n$", False)Can you provide a minimal example replicating the error you encountered? |

Sorry the |

Thank you. That reproduces the error: >>> GitWildMatchPattern.pattern_to_regex("!")
Traceback (most recent call last):

File "/home/.../python-path-specification/pathspec/patterns/gitwildmatch.py", line 112, in pattern_to_regex
if not pattern_segs[-1] and len(pattern_segs) > 1:

We've addressed the issue that GitWildMatchPattern would raise a cryptic IndexError for invalid git patterns. Instead, we raise an informative exception explaining that an invalid pattern was encountered. This exception is raised for at least the following patterns: - `!` - `\`

I encountered an exeption in pathspec when
This line gives an error when the string "!\n" is passed, specifically due to a stray linebreak in the .gitignore file.
https://github.com/cpburnz/python-path-specification/blob/master/pathspec/patterns/gitwildmatch.py#L112
I am not sure what the expected behaviour is here, but it may be best to ignore rather than crash on the line.
