Things to do

Mostly for my own reference, but if anyone else feels like helping out …

• Tests (this is already more complex than I like code without tests to be)
• Handle Windows line endings in files correctly
• Validate path and commit on initial invocation
• Die more gracefully on SIGINT

Display more data

• Line numbers
• Author names (or initials?)
• Display configuration (either with command line flags, or with git config settings, or both)

User interface

• Horizontal scrolling (based on Less)
• Support for more Less keys (especially those with modifiers)
• Move to previous/next commit that changed the current line
• Jump to first/last commit that changed the file
• Jump to first/last commit that changed the current line
