Patron messages containing carriage returns, line feeds, or CRLF
combinations can break SIP protocol communication since CR is used
as the SIP message terminator. This causes message parsing failures
and protocol errors in self-check systems.
The previous regex only handled single carriage returns (\r),
missing Windows CRLF (\r\n) and Unix LF (\n) sequences.
This patch normalizes all line ending variations to spaces to
prevent SIP message corruption while preserving message content.
Test plan:
1. Go to a patron record and click "Add message"
2. Select "Add message for OPAC..." from dropdown
3. In a text editor (e.g., Word), create a message with line breaks:
"This is line one[Enter]This is line two[Enter]This is line three"
4. Copy and paste this multi-line text into the message box and save
5. Run the SIP emulator: misc/sip_cli_emulator.pl
6. Execute a patron information request for this patron
7. Before patch: Observe message breaks at line endings, corrupting
the SIP response
8. Apply patch and restart SIP server
9. Repeat steps 5-6
10. After patch: Verify the message appears as single line with
spaces replacing line breaks: "This is line one This is line two
This is line three"
11. Test with different line ending types (Windows, Mac, Unix) to
ensure all variations are handled correctly
