fix: support line removal in patch tool

[ErikBjare]

The patch tool now properly handles empty content between ======= and >>>>>>> UPDATED, allowing for line removal in patches.

This is done by:

• Splitting patch content in multiple steps
• Special handling of the case where UPDATED marker follows immediately after DIVIDER
• Maintaining compatibility with existing patch formats

• Draft comment:
  Consider using re.search or re.match to check for the presence of patterns before splitting, to improve efficiency. This applies to lines 122, 126, and 139.
• Reason this comment was not posted:
  Confidence changes required: 50%
  The code uses re.split multiple times, which can be inefficient. Using re.search or re.match might be more efficient for checking the presence of a pattern before splitting.
