Summary

Fixes #619

This PR fixes an issue where Python Fire incorrectly removes parts of command-line arguments containing unquoted # characters.

For example, passing qgm#123 previously resulted in qgm. With this change, the original argument is preserved.

Changes

• Updated fire/parser.py to detect unquoted hash characters using Python's tokenizer.
• Prevented the literal parser from treating these characters as comments.
• Preserved existing parsing behavior for quoted strings, lists, and dictionaries.
• Added regression tests in fire/parser_test.py to cover the affected cases.

Testing

Added test cases covering:

• Unquoted arguments such as qgm#123 and a#b#c.
• Arguments beginning with #.
• Quoted hash characters inside lists and dictionaries.

The isolated parsing checks passed. The full test suite has not yet been run.

Files Changed

• fire/parser.py
• fire/parser_test.py
